Rethinking Adam as the First Created Human

Whether you’re a Christian or not, I’m going to guess you’re familiar with this picture:

First there was nothing, then God made Adam, then Eve, and from those two every human being who ever lived is descended.

It’s a pretty clean timeline. Simple, easy to teach in Sunday school… The text even seems to indicate this is the way of things, if you read it a particular way.

The only problem? The Bible never explicitly says Adam was the first biological human. Various texts throughout the Bible can naturally be read genealogically or covenantally rather than biologically exhaustive.

What Genesis does clearly say is that Adam was the first man placed in a unique location with a unique relationship with God. And when we slow down and pay attention to the details, a picture emerges where Adam is not the first human being, but the first covenant representative. 

We’ll explore much of Genesis 1-4 in this article. In the process, I will submit a view that most of you will probably consider extreme and unfounded:

Adam as the first human creates a theological contradiction about sin’s nature. And subsequently, defenses for Adam as the first human redefine sin into biology, sociology, or pragmatism.

All I ask is that you consider my thesis, and the arguments I’ll use to support it, before casting judgment. I’m confident that, at the end of this article, you’ll realize that the view of Adam as the progenitor of mankind isn’t as grounded as it initially sounds.

Before we dive in, though, I do want to affirm a few key points:

• Adam is a real, historical figure.
• His existence, and his sin, matter.
• We are all born with a sin nature, because we are all “in Adam” covenantally. 

Christians throughout history have not always agreed on how Adam functions in relation to humanity. Some early interpreters understood him primarily as the covenant head and representative of humanity rather than insisting the text answers modern biological questions. My goal here is not to invent a new doctrine, but to re-examine what Scripture itself requires us to affirm.

So, let’s walk through the biblical clues that point in that direction.

Part I: Textual Plausibility

Before I dive into my primary arguments, I want to work through the first four chapters of Genesis to demonstrate why they don’t have to be read with Adam as the first man. And why, in most cases, it makes more sense if you don’t. So let’s jump into Genesis 1.

Genesis 1 Describes Humanity, Not Just One Couple

Genesis 1 starts by describing the six day creation account. The first 25 verses of this chapter alone deserve their own article, but we’ll start at verse 26 here, just as God is reaching the final stage of creation:

“Then God said, ‘Let us make man in our image, according to our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth.’ God created man in His own image, in the image of God He created them; male and female He created them. God blessed them; and God said to them, ‘Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the sky and over every living thing that moves on the earth.’ Then God said, ‘Behold, I have given you every plant yielding seed that is on the surface of all the earth, and every tree which has fruit yielding seed; it shall be food for you; and to every beast of the earth and to every bird of the sky and to every thing that moves on the earth which has life, I have given every green plant for food’; and it was so” (Gen 1:26-30).

Scholars call this passage the “dominion mandate,” and if you look at it closely, you’ll notice some interesting things (bolded above). 

First, most notably, no names are given here. God creates humankind, but as of yet, there’s no one named Adam or Eve. In fact, when looking at the Hebrew, the passage reads like this: “Let us make ha’adam in our image…” which is a collective noun meaning “the human” or “humankind.” It’s only later that Adam is used as a proper name. Genesis 1 is describing the creation of humanity as a category, not introducing an individual man by name.

You might also have noticed the immediate plurality of humankind. The text moves to plural language right away, and we see verbiage like “like them rule” and “He created them” and “Male and female He created them.” This differs from the singular “He created him (Adam)” that we would expect if Adam truly was the first human. The focus is not on a solitary man later joined by a woman, but on humanity as a unified image-bearing community from the outset.

Even more interesting, in my opinion, is the global mandate given by God to fill the earth and rule over its inhabitants, including the fish of the sea. The garden of Eden was almost certainly on a mountain (according to Ezekial 28), and would therefore be far away from any ocean, lake, or sea. This commission is not a local gardening assignment; it’s a species-wide vocation.

This plays into the other aspect of the global mandate: multiply and fill the earth. Again, this would be a difficult task for two people living within the confines of a garden.

Those of you who are familiar with Genesis might say that my arguments are irrelevant because Genesis 1 and 2 don’t necessarily fall within chronological order. There’s a view that believes Genesis 2 is the author’s way of retelling events that took place in Genesis 1, as a way to explain the original creation of mankind in greater detail. I disagree with this view, as I’ll explain in the next section of this article, but even if that was the case, it wouldn’t explain the mandate to rule over the fish of the sea when Adam and Eve are enclosed within a garden on a mountain.

Needless to say, Genesis 1 reads like the creation and commissioning of the human race as a whole.

Genesis 2, by contrast, continues the story. It does not begin with oceans, skies, and ecosystems, but with land, a garden, and a man placed there for a specific task. The scope narrows from global to local, from humanity to a priestly figure in a holy place.

Genesis 1 answers the question, “Why did God create humanity?”

While Genesis 2 begins to answer a different question: “Why did God place one particular man in a sacred garden?”

Again, while this doesn’t prove that Adam wasn’t the first human, it does establish that he didn’t need to be.

Genesis 2 is Not a Retelling — It’s a Consecutive Sequential Narrative

Things can feel pretty straightforward as you read Genesis 1. God turns chaos into order, creating domains during the first three days (light vs darkness, expanse between waters, dry land) and inhabitants during the latter three days (luminaries, sea creatures and birds, land dwellers). Humankind is clearly established during the sixth day, and if the story ended there, things would be much simpler – if more vague.

However, Genesis 2 continues the creation narrative, where God forms a man that we all know as “Adam,” and places him in a garden within the land of Eden. You’ll notice that I said this chapter continues the creation narrative; it doesn’t just zoom in on the events of the previous chapter.

There are several reasons why this is the case, but I’ll focus on two of the most compelling.

The Toledoth Formula

A toledoth indicates a record of descent or lineage, especially within the Torah, and particularly within the book of Genesis. In fact, the word toledoth itself means “generations.” The first use of this formula is found in Genesis 2:4, which says:

This is the account of the heavens and the earth when they were created, in the day that the LORD God made earth and heaven.

Later examples include:

Genesis 6:9 – “These are the records of the generations of Noah.”

Genesis 11:27 – “Now these are the records of the generations of Terah.”

Genesis 25:19 – “Now these are the records of the generations of Isaac, Abraham’s son…”

That’s not even half of them, but you get the gist. Ultimately, I would recommend seeking out all of the toledoths in Genesis and comparing them for yourself; if you do so, you’ll notice something interesting. In every instance where a toledoth is used, the following verses always introduce what comes next – not a recap. If the toledoth formula consistently introduces what follows everywhere else in Genesis, it would be unusual for Genesis 2:4 to function as a lone exception. The burden of proof would lie with anyone arguing that it suddenly shifts direction here.

Of course, some argue that Genesis 2:4 functions differently because it refers to “the heavens and the earth” rather than a person. But even in those cases, the toledoth formula introduces what develops from the subject, not a replay of what has already been narrated.

Hebrew Grammar

Just like English grammar, Hebrew grammar contains a variety of tenses. I’ll try to keep this as beginner friendly as possible, but suffice it to say that Genesis 2 is written predominantly with wayyiqtol verb forms, which indicate the classic Hebrew narrative past. In layman’s terms, this form normally advances the storyline using a structure similar to: and then… and then… and then…

While Genesis 2 includes occasional background statements, its dominant structure is sequential narrative. The repeated wayyiqtol verbs move the story forward step by step, just like the rest of Genesis’ historical accounts. This reads like a consecutive sequential narrative about a specific man in a specific location. Not a poetic retelling of Day Six from a different angle.

Questions about whether Genesis describes humanity as a whole before focusing on a particular man are not unique to modern readers. Jewish and Christian interpreters long before modern science wrestled with how these chapters relate, sometimes reading them as a movement from humanity in general to a specific priestly figure placed in sacred space.

Genesis 3:20 Says Eve is the Mother of Humanity?

Along with Acts 17:26, Genesis 3:20 is one of the strongest textual arguments for Eve as the sole mother of all humankind.

At least, that’s how it appears on the surface.

In reality, it’s not as straightforward as it sounds to our modern ears, and I’ll explain why. But first, the verse in question:

Now the man called his wife’s name Eve, because she was the mother of all the living. 

Sounds pretty cut and dry at face value, but let’s slow down and look at it from the storytelling framework of Genesis and the Hebrew itself.

Overall, the verse is an etymology, not a genealogy. The Hebrew name ḥawwāh (Eve) is connected to the root ḥayah, which means life / living. So the narrator is doing a wordplay explanation:

Adam names her Life-giver because she is “mother of all living.”

In Genesis, these naming explanations almost never function as biological claims. Instead, they usually function as theological identity statements.

For example:

• Noah → “rest/comfort” (Gen 5:29) is not literally the source of all rest
• Babel → “confusion” (Gen 11:9) is not literally the origin of all languages
• Israel → “strives with God” (Gen 32:28) is not biologically descriptive

So grammatically, Gen 3:20 reads closer to:

“She will be the source of life for humanity” rather than “Every human chromosome traces back exclusively to this one woman.”

Eve being the source of life for humanity makes sense given the context. Adam names her right directly after they were cursed for sinning, which includes God’s proclamation that Eve’s descendant would crush the serpent’s head. The promised Messiah, the woman’s seed, would be a source of life for humanity. Rather than a biological statement about human ancestry, it functions as a declaration of hope: life for humanity will come through the woman. This is a trajectory Christians later understand as fulfilled in Christ.

In Genesis 4, Cain’s Fear Makes More Sense if Other Humans Exist

Genesis 4 delves into the tale of Cain and Abel, which takes place after Adam and Eve sin and are cast out of the Garden of Eden. To paraphrase the beginning of the story, Cain (a farmer) and Abel (a shepherd) both give an offering to the Lord. Abel’s offering is pleasing to God, while Cain’s is not.

In anger and jealousy, Cain rises up and kills his brother. 

God responds with a curse: “Now you (Cain) are cursed from the ground… When you cultivate the ground, it will no longer yield its strength to you; you will be a vagrant and a wanderer on the earth” (Gen 4:11-12).

This curse is significant. As a farmer, Cain’s identity was tied to the soil. Now the very ground he worked will resist him, and he won’t be able to sustain himself through agriculture.

Cain feels crushed by the weight of this punishment, and says something interesting in response to God’s decree: “Behold, You have driven me this day from the face of the ground; and from Your face I will be hidden, and I will be a vagrant and a wanderer on the earth, and whoever finds me will kill me.”

Cain is clearly worried about being killed, and God takes this concern seriously. So seriously, in fact, that He “appointed a sign for Cain, so that no one finding him would slay him” (Gen 4:15b).

Who is Cain worried might kill him? 

If Adam and Eve were the only progenitors of humanity, then at this point the world’s population would consist exclusively of his immediate relatives: siblings, nieces, nephews, perhaps a few extended generations at most.

And yet Cain speaks as if he expects to encounter hostile strangers.

Even more striking: God does not correct him. He does not say, “There are only a handful of you.” Instead, He appoints a sign to protect Cain in Genesis 4:15:

So the Lord appointed a sign for Cain, so that no one finding him would slay him.

God treats the threat as real.

If the danger was merely a small cluster of close relatives living in proximity, relocation would be the obvious solution. Yet the narrative does not present Cain’s fear as irrational or exaggerated. It presents it as credible.

Then Cain departs, moving east of Eden to the land of Nod. Immediately we read that he has a wife, he fathers a son, and he builds a city and names it after his son. The creation of a city raises interesting questions, like, “Why would Cain build a city (‘ir) just for his family, or perhaps a small community?” and “Where would the labor to creates such a city come from?”

The existence of a wife is also interesting. The common explanation is that she was his sister, but the text never identifies her as such, nor does it treat her as unusual. 

And even if she was his sister, greater problems arise, which we’ll talk more about in the next section.

Contradictions in the Traditional View

Now that we’ve established some textual plausibility for how you can read Genesis without Adam as the first created human, let’s move into the territory of why you shouldn’t. There are necessary implications that come from Adam being the first human. And as I stated in my thesis, these implications create defenses that redefine sin in a way that should make any Christian uncomfortable. This is no longer just an alternate view on the origin of mankind; it’s an examination of hamartiology and the unchanging nature of God.

The Moral Problem of Incest in a “Very Good” Creation

Most of you are probably familiar with this line of reasoning, and perhaps you’ve heard arguments supporting it.

If Adam and Eve were the progenitors of humankind, their children would have needed to form incestuous relationships with each other to “be fruitful and multiply.”

There is no way around that.

And yet, a detail that’s often overlooked is that this command was given before the Fall. That means, if sibling reproduction was necessary, it would have been part of a creation God declared “very good.”

This creates a problem that I’ll describe in detail over the remainder of this section: Moral categories reflect creation structure; creation structure forbids incest; therefore incest cannot be a creation mechanism.

Ultimately, this is a matter of redefining sin. Adam not being the first human is a related, but secondary, matter.

Leviticus 18

Leviticus 18 has some pretty clear words for how God views incest. Particularly in verse 6 which reads: “None of you shall approach any blood relative of his to uncover nakedness; I am Yahweh.”

The chapter continues by specifying what that means: sisters (v. 9), half-sisters (v. 11), aunts (v. 12–13), daughters-in-law (v. 15), and more. These acts are not treated as minor infractions. By the end of the chapter, they are grouped among practices that defile a land, including acts like child sacrifice, homosexuality, and bestiality. Verse 26 refers to them collectively as abominations.

I recognize that the word for abomination (to’evah) is used to refer to a variety of things, including wearing mixed fabrics (Deut 22:11) and eating certain animals (Lev 11). Therefore, to’evah alone is not enough to prove that incest is ontologically sinful. However, the fact that God views it as covenantal defilement is telling in relation to his overall stance on the matter. But beyond this point, sexual sin, including incest, is viewed as immoral across the Testaments (1 Cor 5:1), and is therefore not limited to Israel’s holiness code.

Ceremonial Commands vs Moral Categories

There are some who would argue that incest was fine in the time of Adam and Eve because the Law had not been handed down to Moses yet. There wasn’t a distinct people (Israel) that God wanted separate from the nations around them. As such, the concept of “progressive revelation” is often cited in defense of early incestuous relationships, meaning that God progressively revealed his standard for sin over time. If you happened to live in a time before God revealed something as sin, you’re effectively off the hook.

But that’s not how sin works. Cain was held responsible for murdering his brother long before the sixth commandment was given to Moses. Angels were held accountable for their sexual sin in Genesis 6 and subsequently bound in chains of darkness (2 Peter; Jude). Sodom and Gomorrah were wiped out for their sexual sin before the Law was given as well. Clearly, God still views sin objectively (and judges people for it) even before it’s spelled out in the Law.

So then, the question becomes: Is incest ontologically sinful, or did God merely designate it as a way for Israel to remain distinct from the surrounding nations?

I’ll refer back to 1 Corinthians 5:1 again:

It is actually reported that there is immorality among you, and immorality of such a kind as does not exist even among the Gentiles, that someone has his father’s wife.

You’ll notice a few interesting things here. First, we have an example of a man sleeping with his father’s wife – an action that Leviticus 18 categorically labels as “incest.” It’s also referred to as “immoral”, specifically a kind of immorality that doesn’t even exist within the Gentiles: people not under the scope of the Law.

Here, incest isn’t being portrayed as something purely ceremonial. It’s not just specific to Israel, as a way for them to distinguish themselves as “separate” amongst the nations. Instead, it’s being placed into a moral category: genuine sin that is contrary to God’s will and nature.

Denying the moral weight of incest, just because it falls within Levitical law, is special pleading. Anyone claiming incest is merely ceremonial has to explain why it’s grouped with child sacrifice and treated as defiling for the nations.

And ultimately, if incest were necessary in Genesis 1-2, it would not merely be permitted; it would be part of the creational structure God called “very good.” That differs categorically from later covenant distinctions like dietary laws, and directly contradicts Genesis 2:24, which we’ll look at next.

Genesis 2:24

Here’s what I consider to be the most striking argument for why incest wasn’t originally allowed by God or part of his original design. Within the creation account itself, God establishes the proper model for marriage:

For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh.

There are three distinct categories of people here:

• The child (the man getting married)
• The parents (father and mother)
• The spouse

The language is striking. A man will leave his father and mother (where his sister would also be) and be joined to his wife; and they shall become one flesh. Marriage is depicted as creating a new household unit distinct from the parental household. Put another way, Genesis 2:24 establishes that marriage creates a new kinship identity distinct from one’s birth kinship. Sibling marriage blurs that boundary by collapsing the distinction between (1) the kin you come from (family of origin), and (2) the kin you form (new household). Genesis 2:24 assumes a movement from one kinship unit to a separate one. Sibling marriage does not involve crossing kinship boundaries; it internalizes them.

Considering this structure falls within a “very good” creation account, prior to the Fall, it’s a distinction that appears to be embedded in the creation order itself. 

Not merely later covenant law.

To summarize: In a “very good” creation, you can’t have a defined structure for marriage that fundamentally excludes incest, and have incest be an embedded requirement for reproduction.

Incest is not first prohibited in Leviticus; it’s first made impossible by the creational design of marriage itself.

Amnon and Tamar

I’ll end my argument with a look at the story of Amnon and Tamar, found in 2 Samuel 13. This passage depicts an account of rape and incest between half-siblings, and what Tamar has to say during the account is crucial for understanding why incest is ontologically sinful. She says in verses 12-13:

No, my brother, do not violate me, for such a thing is not done in Israel; do not do this disgraceful thing! As for me, where could I get rid of my reproach? And as for you, you will be like one of the fools in Israel.

There is no question that rape is central to the story. The text emphasizes his force, her resistance, and his refusal to listen. The Hebrew verb used for “violate” elsewhere describes sexual humiliation and oppression. Any reading that minimizes the violence of the act would be irresponsible.

But the question for our purposes is more specific:

Is the moral horror of the passage only rape, or is incest itself part of what makes the act so reprehensible?

I would propose that a close reading suggests it is both.

What’s often overlooked is that Tamar’s strongest moral protest occurs before Amnon physically forces her. When he tells her to lie with him, she immediately responds: “No, my brother, do not violate (humiliate) me, for such a thing is not done in Israel. Do not do this disgraceful thing” (v. 12).

At this point in the narrative, the physical assault has not yet happened. Amnon has propositioned her, but he has not yet overpowered her. Tamar is responding to the sexual proposal itself. And instead of saying, “Don’t force me,” she says, “This is disgraceful… This is not done in Israel.”

She frames the proposed sexual act as morally shameful before force is applied.

If you read through 2 Samuel 13, you’ll also notice that the narrator repeatedly reminds us of their relationship: “I am in love with Tamar, the sister of my brother Absalom.” (v. 4), “Please let my sister Tamar come give me some food to eat…” (v. 5), “Please let my sister Tamar come and make me a couple of cakes…” (v. 6), “Go to your brother Amnon’s house…” (v. 7), “So Tamar went to her brother Amnon’s house…” (v. 8), “Tamar took the cakes…into the bedroom to her brother Amnon.” (v. 10), “Come lie with me, my sister.” (v. 11), “No, my brother, do not violate me…” (v. 12).

Almost every verse in this account explicitly reminds the reader of their sibling relationship. This is not incidental. The narrative wants us to feel the relational boundary being crossed. The horror is not only that a woman is assaulted, but also that a brother violates a sister. The kinship category is not background information; it is part of the moral structure of the story.

If the sin were merely violence, the sibling emphasis would be unnecessary. But the author continually foregrounds it.

One objection often raised is Tamar’s plea: “Speak to the king, for he will not withhold me from you” (v. 13b).

At first glance, this sounds like she is suggesting marriage as a legitimate solution, but several factors caution against that reading.

First, Tamar is speaking under extreme duress. She’s isolated, vulnerable, and trying to prevent an imminent assault. Offering marriage may function as a delay tactic, and an appeal to procedure rather than violence.

Second, the narrative never presents such a marriage as viable or righteous. After the rape, no one suggests legitimizing the union. Amnon immediately rejects her, and the text never treats marriage as a genuine moral possibility.

Third, under the Law, sexual relations with a half-sister were explicitly forbidden. Tamar’s statement cannot be read as a theological endorsement of sibling marriage; it reads far more naturally as desperate negotiation in the face of impending violation.

The story of Amnon and Tamar does not allow us to isolate rape from incest as if only one were morally relevant. The act is horrific because it is both violent and incestuous.

• Tamar condemns the sexual proposal itself before force occurs.
• The narrative repeatedly emphasizes their sibling relationship.
• The language used carries moral weight beyond mere assault.
• No legitimate pathway for such a union is ever entertained.

The text assumes incestuous sexual relations are disgraceful, and that assumption is never presented as a new moral development. It is treated as self-evident.

When we step back and place this alongside the explicit prohibitions of Leviticus 18 and the reaffirmation of sexual boundaries in the New Testament, the cumulative picture is difficult to ignore: incest is not treated as a temporary boundary marker or a culturally relative taboo. It is treated as a violation of something deeply embedded in the moral structure of God’s design.

The story of Amnon and Tamar does not stand alone as a proof-text. But it fits seamlessly within the broader biblical witness: one that consistently presents incest not as conditionally problematic, but as inherently shameful.

Pulling it All Together

So, here’s the dilemma. If Adam and Eve were the first and only humans, then sibling unions weren’t just tolerated… They were necessary. Necessary for multiplication and the survival of humanity.

Necessary for obedience to God. And if they were necessary before sin entered the world, then they would have been embedded into a creation God declared “very good.”

Yet, centuries later, the same type of relationship is described as defiling and abominable. How does that square with an unchanging God?

When it’s all said and done, my position here is very straightforward: A “very good” creation would not be built on a reproductive system that requires a structure later revealed to be immoral.

Right and wrong are not arbitrary decrees. They are rooted in God’s character. If something is morally wrong in Genesis 2, Leviticus 18, 2 Samuel 13, and 1 Corinthians 5, it is wrong because it contradicts God’s holy nature. And if that is true, then it cannot have been woven into the fabric of a “very good” creation as a necessary reproductive mechanism. A creation declared “very good” would not require a structure later revealed to be morally defiling.

For that reason alone, Adam and Eve could not have been the first progenitors of humankind.

A Reassurance of Doctrine

Before we carry on, I want to pause to give a reaffirmation of traditional doctrine. I want to assuage any fears that I’m throwing out or undercutting foundational doctrines like original sin, the universality of sin, atonement, the authority of Scripture, the image of God, or the Fall. I’m going to briefly address all of these, and then finish by looking at Romans 5 and 1 Corinthians 15.

Original Sin

The Fear: If Adam isn’t the first biological human, then humanity didn’t descend from one man → therefore sin isn’t inherited → therefore Paul is wrong → therefore the gospel breaks.

Why the Doctrine is Preserved: Paul’s argument in Romans 5 is representational, not genetic. In the chapter, he contrasts two covenant heads:

• Adam → death spreads to those “in him”
• Christ → life spreads to those “in him”

No one thinks we’re saved by sharing Jesus’ DNA. Therefore, the parallel requires the same category for Adam.

The doctrine survives (and arguably becomes clearer) by framing it as: Humanity falls through covenantal headship, not biological contagion.

I’m not denying original sin. I’m simply relocating it from biology to representation. More on this later.

Universality of Sin

The Fear: If some humans existed outside the garden, maybe some weren’t fallen.

Why the Doctrine is Preserved: Scripture never argues that all sin because all share Adam’s DNA, as mentioned in the previous point. Instead, it argues that all sin because all share Adam’s condition. Even in traditional theology, we don’t personally commit Adam’s act; we enter a corrupted human condition.

My model still fully affirms:

• universal corruption
• universal death
• universal need for salvation

I’m only challenging the biological mechanism, not the universality.

The Need for Christ’s Atonement

The Fear: If Adam’s sin isn’t biologically transmitted, Christ’s substitution may not apply to everyone.

Why the Doctrine is Preserved: The symmetry Paul draws is covenantal, not genetic. We aren’t saved because Jesus shares chromosomes with us. We’re saved because He represents humanity before God.

So the parallel still works perfectly:

Head	What He Does	How It Applies
Adam	Brings death	participation in humanity
Christ	Brings life	participation in Christ

My model actually protects the logic of salvation working the same way condemnation does: representationally.

Biblical Authority

The Fear: If Adam isn’t the first human, the Bible is wrong.

Why the Doctrine is Preserved: My argument is precisely that Scripture never actually states that claim;
it’s an inference layered onto the text. So, I’m not revising Scripture; I’m revising a traditional interpretation.

The Image of God

The Fear: If humans existed before Adam, were they not in God’s image?

Why the Doctrine is Preserved: Genesis 1 already gives the image to humanity as a category. Genesis 2 gives Adam a priestly vocation.

So Adam becomes, not the first image-bearer, but the first covenant priest-king.

Nothing about human dignity or worth changes.

The Fall

The Fear: If people existed outside Eden, did the Fall even matter?

Why the Doctrine is Preserved: The Fall is about humanity’s relationship with God, not the start of molecules decaying.

My model preserves:

• a real historical fall
• a real entrance of spiritual death
• a real change in humanity’s standing before God

It just means the Fall is judicial and relational rather than genetic mutation.

Romans 5 & 1 Corinthians 15

The majority of Christians in the last 1,600 years have followed Augustinian tradition, reading Romans 5 and 1 Corinthians 15 as proof that Adam must be the first man. They read 1 Corinthians 5:22a, and think it must be so.

“For as in Adam all die…”

How else could we be “in Adam,” if not biologically? This is the basis for Augustine’s view of inherited guilt.

However, all one has to do is finish reading the verse to understand that biology is not the only answer.

“…so also in Christ, all will be made alive” (1 Cor 15:22b).

We have symmetry in wording here: “in Adam” followed by “in Christ.” Paul defines one union using the other. Therefore, they must belong to the same kind of relationship: covenantal participation, not genetic transmission. Perhaps ironically, this actually strengthens federal headship.

It doesn’t deny it.

This is especially true since Christ didn’t have biological descendants. And even if he did, that’s still not a good reading of the text. Instead, salvation comes to all “in Christ” through his covenantal headship; likewise, all are “in Adam” through his covenantal headship. This is what Paul means when he says that Adam is “a type” of Christ (Rom 5:14).

Parallelism defines meaning. Paul explains Adam using Christ, not Christ using Adam. So, if “in Christ” is referring to covenantal union, then “in Adam” must also be covenantal union. 

I could go into greater detail on this topic but suffice it to say that Adam does not need to be the first human for all of us to be subject to sin and death. The core doctrines remain unchanged: humanity is fallen, Adam is the representative head of that fall, and Christ is the representative head of redemption.

This still falls cleanly within Christian orthodoxy.

Common Objections

There are objections, as you might expect, to a co-Adamic or a pre-Adamic (my position) view of humanity. There are several dogmas that come under fire if Adam is not the first human, such as Augustine’s view of original sin – that we inherit Adam’s guilt through real descent, which later became blended with covenant headship.

I believe there are a lot of problems with Augustine’s theory, which I’ll save for another article. I also don’t deny that we are all born with a sin nature. 

But Adam does not need to be the first human for us to believe that all sin and fall short of the glory of God.

This is deeply uncomfortable for many people, and I have a great deal of sympathy for them, because shaking a pillar of traditional theology can be a scary endeavor. While I respect tradition, it’s not infallible, and should not be accepted simply because it’s tradition.

I’ve encountered many people who staunchly defend the dogma of Adam as the first human. They usually think they have to, or their entire worldview will fall apart, but what they don’t realize is that many of their arguments are actively condoning what they fear the most.

Many of these arguments share a pattern. Each one relocates morality into a secondary category, like genetics, social development, legal codification, or programmatic necessity, rather than grounding it in creation order. The problem is not merely that these arguments fail, but that they unintentionally reshape what sin is.

That being said, here are some of the most common rebuttals and my responses to them.

In the Beginning, Humanity was Genetically Pure, so Incest wasn’t a Problem

This is the argument that I hear the most to justify the necessity of incest with Adam and Eve being the first couple. And, ironically, this position redefines sin as biological harm rather than moral disorder.

In using this argument, people don’t understand that they’re conceding the wrong category. The logic is that:

• Early humans = no mutations → incest fine
• Later humans = mutations accumulate → incest harmful → God forbids it

Notice what just happened there. Incest stopped being a moral violation and became a medical risk, making the command about birth defects and not holiness, order, or creation. So hypothetically, if two siblings could guarantee healthy children today, this argument would say the union of those siblings wouldn’t be wrong anymore.

If incest becomes sinful only after mutations accumulate, then morality tracks biology. But Scripture grounds sexual ethics in created relationships, not medical outcomes. Therefore, the argument redefines sin rather than explains it.

Since There was No Other Way to be Fruitful and Multiply, God Temporarily Suspended the Restriction on Incest Until There was a Sufficient Population

There’s a similar flaw in this argument as there was in the previous one: it bases morality on population size, instead of the unchanging nature of God.

We’ve already established earlier in this article that Scripture consistently treats incest as violation of created kinship order rather than merely covenant legislation. What this argument purports isn’t just that God temporarily turned a blind eye to sin out of necessity; it’s that God himself made things this way, called it “very good,” and then later referred to it as detestable.

But, putting that aside, let me ask you a question. If God initially allowed incest out of necessity for population growth, at what point did it become sinful? When there were 4 people? 40? 4,000?

Either the act was morally good, or the act was morally evil but commanded. Whichever route you choose, you’re left with a moral change in God or a divine command of evil.

Neither flows from the character of God. Instead, this argument redefines sin as depending on something as arbitrary as population numbers.

Incest Wasn’t Definitionally Possible Yet, Since Society was Undeveloped

A continuation to this argument might be: “Just as you can’t have property laws without property, you can’t have incest laws without society.”

This is an interesting argument, but it falls flat as soon as you think about it. Incest in Scripture is not defined socially: it’s defined relationally (“your sister,” “your mother,” etc.), which means that Genesis presents society as emerging from families, not families from society. You don’t need civilization to have family structure. Abel was called Cain’s brother well before any mention of civilization appears in Genesis.

I agree that you can’t have property laws without property. But when it comes to incest, all you need is a dad, a mom, and one or two children for it to be a real possibility. That’s a standard nuclear family, and it’s exactly what we would have seen if Adam and Eve were the progenitors of humanity. Therefore, all this argument does is redefine sin into a matter of sociology.

The Law Hadn’t Been Given to Moses Yet, so People Couldn’t Actually be Held Responsible for Their Behavior

I won’t spend too much time on this one, since it’s pretty straightforward. Instead, I’ll leave you with what Paul says in Romans 2:12-16:

“For all who have sinned without the Law will also perish without the Law, and all who have sinned under the Law will be judged by the Law; for it is not the hearers of the Law who are just before God, but the doers of the Law will be justified. For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them, on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus.”

The Law passed down to Moses wasn’t necessary to assign guilt, because we all have the Law written in our hearts. Therefore, people can be (and were) held responsible for their sin, even if they have no knowledge of the Law.

Here are a few examples of God judging people before Sinai:

• Cain was held responsible for killing his brother.
• Humanity was judged with the Flood because they were exceedingly violent and evil.
• Sodom and Gomorrah were wiped out because of their sexual sins.

The Mosaic Law didn’t introduce moral knowledge, but rather, it formalized it. All this argument does is move the goalposts from where the Bible has clearly set them.

Before the Fall, Adam and Eve’s Children Didn’t Need to Marry and Reproduce

This argument tries to get around the problem of incest by saying it wasn’t necessary before the Fall. God never intended for Adam and Eve’s children to marry and reproduce; only Adam and Eve would continue to procreate, since they and their children would (theoretically) just live forever. At some point, the world was bound to be filled.

However, there are a lot of gymnastics that need to take place for this argument to work, causing it to fall short for many reasons. I’ll just focus on Genesis 2:24 again.

This verse says that a man will leave his father and mother to be united to his wife, and they’ll become one flesh (marriage). Remember that this is said before the Fall.

The intention was for children to leave their parents to create their own families. Since Adam and Eve didn’t have a father or mother, this verse has to relate to their descendants.

Final Thoughts

For most of my life, I never questioned the idea that Adam had to be the first biological human. I inherited it the same way most of us do: not because I carefully examined the text and concluded it demanded that reading, but because it was simply the way the story was always told.

But the more closely I read Scripture, the more I noticed something surprising. The Bible spends far more time explaining what Adam means than explaining where Adam sits in a biological timeline.

• Genesis emphasizes vocation, relationship, and representation.
• Paul emphasizes headship and participation.
• The prophets emphasize covenant failure and restoration.

Yet much of our modern discussion has centered on genetics.

This article hasn’t attempted to prove an alternative human origin story, nor to settle every scientific or historical question. My aim has been much narrower: to ask whether Scripture itself actually requires Adam to be the first biological human, and to examine the theological consequences of insisting that he must be.

Along the way we encountered tensions:

• A creation declared “very good” that appears to require something later condemned as immoral.
• A marriage structure embedded in creation that assumes distinct kinship boundaries.
• A global humanity in Genesis 1 contrasted with a local priest in Genesis 2.
• A New Testament theology that consistently speaks in terms of representation rather than biological transmission.

Individually, any one of these might be explainable. Together, they invite reconsideration.

If I am wrong, then Scripture itself should gently correct me, not tradition, and not fear of unfamiliar conclusions. And if I am right, then Adam’s importance is not diminished but clarified. He is not less than we thought; he is more precise than we assumed: not merely the first man chronologically, but the first man covenantally. Adam was the representative human placed in sacred space on behalf of humanity.

Either way, the center of the Christian story remains unchanged.

Humanity is fallen.
Sin is real.
We cannot heal ourselves.
And the hope of the world is still found in the obedience of another representative man.

The discussion about Adam ultimately matters because it shapes how we understand Christ. But our confidence has never rested in the exact mechanics of how humanity fell; it rests in the certainty that God has acted to restore it.

There is much more that could be said, and many questions this article hasn’t addressed. That’s inevitable with a topic this old and this layered. My goal wasn’t to end the conversation, only to show that faithful Christians can read the same text carefully and arrive at a different conclusion without abandoning the gospel that text proclaims.

If nothing else, I hope this encourages you to return to Scripture itself, slowly, patiently, and without assuming the answer ahead of time. The Bible is sturdy enough to be read honestly.
