Who Were the People Cain Met?

The companion to this page, Cain and the Cainites, argues that Genesis 4 sends Cain into a world that was already peopled. He fears strangers, finds a wife, and builds a city among people who are not descended from Adam and Eve. That reading takes the chapter’s puzzles as clues to follow rather than problems to explain away. But it leaves one question standing, and it may be the deepest of all: who were they?

It is a question worth facing squarely, because a careless answer may do real harm. This page sets out the answer given in A Timeline of Origins. In short, they were fully human, having arrived biologically, we assume, through the processes of evolution that God guided. Everyone Cain met, everyone he could have met, and every person born from that day to this has been fully human, made in the image of God. What follows explains why that is not a convenient assertion but a considered part of the account. It rests on assumptions about God, about the positions we may assume he would never have placed anyone in, and on convictions drawn from Scripture: that Adam was the first human, and the representative head of all humanity, the one through whom we receive both our being in the image of God and our being, by nature, fallen from his former state of perfection.

A human body, not yet a human soul

The question only bites if we assume “human” means one simple thing. It does not. The people already living east of Eden had fully human bodies. They were, in the language of A Timeline of Origins, biological humans: anatomically modern, the product of the long history the sciences describe, indistinguishable in body from you or me. Their bodies were alive, too, and the Bible may characterise that life as the body’s spirit. What the account asks about is something further: the human soul, which points to the immortality of a person, an inward life that will continue on when the body dies, and which Genesis ties to being made in the image of God.

Whether a human being is finally two things, body and soul, or three, body, spirit, and soul, is an old question, and this page does not need to settle it. The narrower point is enough: a body can be fully human while the human soul, in this sense, has not yet been given. That is what gives the puzzle its shape. Evolutionary science already recognises that there was a time when our biological ancestors were not yet human, and a later time when they were. For anyone who takes humanity to be more than its material, that is only half the matter. It is a biological puzzle, when our bodies became human; but it is also a spiritual one, when, historically, we came to have human souls. This page is about the second.

What the difference would, and would not, look like

In part, the difference would have shown. Some things seem to belong to full humanity alone. Chief among them is the power to bind oneself by a promise, and above all to enter the covenant of marriage, which Genesis presents as the first thing two full humans do together. With that come the moral realities that only make sense among persons: that to take a human life is murder in a way that killing an animal is not; that we owe debts of love to God and to our neighbour; that a person can be wronged, robbed, betrayed. To make and keep a promise is partly a feat of understanding, and a creature that could not make one, or could not grasp what a promise binds, might well have struck us as slow, even dumb, in the things it could neither say nor follow. The lack need not have been hidden.

And yet a great deal could still have been present. There is nothing in Scripture, or in plain reason, that requires the earlier biological humans to have been dull in every respect. They may well have had words, and known that a word can stand for a thing. They may have made and used tools, kept and traded goods, fashioned ornament and pattern we would not hesitate to call art. They may have buried their dead and grieved over them. The archaeological record credits behaviour of just this kind to peoples we do not usually call fully human at all, the Neanderthals among them, and it is no strain to allow as much, and more, to the biological humans this account has in view. What they lacked was not ability across the board, but the particular capacities that belong to the soul, and the soul that stands behind them.

One gift, given to everyone at once

So how was that line crossed? The account is simple, and it is the hinge of everything. At the time of Adam’s sin, around 5100 BC, God gave a human soul to every biological human then alive anywhere on earth, in a single moment. He made the first such soul in one man, Adam, and from Adam he relayed it to all the rest, so that a world which had been full of biological humans became, at a stroke, a world of full humans in his image.

One detail carries a sober weight. The soul God used as his pattern was Adam’s own, and Adam’s, by then, was a fallen soul. So what passed to the whole living race was not only the dignity of God’s image but the fault and the mortality that came with the Fall. This is why Scripture can say that “in Adam all die”, and why, in the same breath, it can hold out that “in Christ all will be made alive” (1 Corinthians 15:22). The gift that made everyone fully human is the very thing the gospel later comes to heal.

Notice where this places Cain. Adam’s sin, and this global gift, come before Cain is even born. By the time he is driven east into Nod, the people he finds there have long since received what he received. They are full humans, every one, and his marriage among them is a marriage of equals.

And notice one more thing, easy to miss and worth saying plainly. Because the soul is a gift and not a thing carried in the blood, every one of us today has among our ancestors those earlier biological humans who lived and died before that day. We are all, bodily, their children. That takes nothing from anyone. Full humanity did not descend to us as an inheritance that some hold more purely than others. It was given, to all alike, at once.

Securing the full humanity of all

Here the account shows its worth. In the terms of A Timeline of Origins, it is a thesis that secures, in theoretical terms, the full humanity of every person alive today. A gradual story, in which full humanity seeps into the species slowly and unevenly, cannot finally do that. It leaves a ragged edge: a stretch of time in which some are in and some are not, in which it is genuinely unclear whether the being in front of you is a person to be loved or a creature to be used. Almost everyone recoils from that, and rightly. We feel, without being taught it, that there is a bright line between a person and an animal, that hunting a whale is not murder, and that putting down a suffering dog is a smaller and different thing than the death of a grandfather. If that line is real, then there was never a living person whose mother was fully human and whose uncle was not.

The account given here secures exactly that. Because the gift was global and given in an instant, there was never a borderline generation, never a household half in and half out, never a moment when a human being had to wonder whether the people over the next hill were kin in God’s image or fair game. And because it fell on everyone then alive, no people that has walked the earth since, on any continent, however early their ancestors set out, can be thought to have missed it. The account devalues no one. That is not a happy accident bolted on at the end. It is the reason the account takes the shape it does.

The claim, and its limits

As everywhere on this site, the claim is offered with humility. That God worked in just this way cannot be proven, and the timing and the mechanism are a hypothesis, not a dogma. But it is a hypothesis that the logic of this site appears to require. It lets the plain reading of Genesis 4 stand, Cain among real people east of Eden, without paying for it in the coin of anyone’s dignity. It keeps faith with the oldest Christian conviction, that every human being without exception bears the image of God. And it answers the question this page began with, the one the last chapter left standing, in the only way that honours both the text and the people it is about: the people Cain met were fully human, as were all he might have met, and as are all their children to this day.
