Caspar David Friedrich — Wanderer above the Sea of Fog, 1818 (Public domain)
Picture a five-year-old girl, crying alone on a street corner. She’s lost. Before anyone can find her, a stranger takes her, kills her, and abandons her body.
Was that evil?
Almost everyone answers yes — immediately, without deliberation. But here’s the harder question: why? And what happens to that answer when we push it to its logical limit?
THE THOUGHT EXPERIMENT
Imagine a terrorist group develops a weapon capable of killing nearly everyone on Earth. They use it. Seven billion people die. The one million survivors unanimously declare the massacre morally good. They pass laws celebrating it. They build monuments to it. Resistance is outlawed.
Is the genocide now good?
Go further. Among the survivors, a 10-year-old girl is raped daily. The majority votes it righteous. Those who try to stop it are arrested and punished as criminals.
Is that rape now morally acceptable?
Most people — atheists included — feel viscerally that the answer is no. Genocide doesn’t become good because a majority approves it. A child’s suffering is not justified by a vote.
But in a purely atheistic, evolutionary worldview: on what basis can you say so?
THE PROBLEM WITH ATHEISTIC MORALITY
If there is no God — no transcendent moral authority above humanity — then morality is simply what human beings collectively decide. There is no court of appeal beyond the crowd.
Darwin himself saw the uncomfortable implication. In The Descent of Man, he wrote:
"If, for instance, to take an extreme case, men were reared under precisely
the same conditions as hive-bees, there can hardly be a doubt that our
unmarried females would, like the worker-bees, think it a sacred duty to
kill their brothers, and mothers would strive to kill their fertile
daughters; and no one would think of interfering."Darwin’s point: moral intuitions are not universal truths. They are the product of evolutionary conditions. Change the conditions, change the morality.
Richard Dawkins agrees. In River Out of Eden, he writes that the universe “has no design, no purpose, no evil and no good, nothing but blind, pitiless indifference.”
If that is true, then our condemnations of genocide and rape are not moral facts. They are preferences — no more objectively binding than a taste in music.
THE HISTORICAL TEST
Atheists passionately condemn slavery, the Holocaust, colonial genocide, and Japan’s wartime atrocities. These condemnations are morally correct. But they are philosophically inconsistent with atheism.
Under an evolutionary worldview, Japan’s military was simply a stronger organism exploiting weaker ones — the engine of natural selection doing exactly what it’s supposed to do. The collaborators who aided Japan for personal gain were optimizing for survival. The patriots who died resisting were organisms that failed to adapt.
That conclusion is monstrous. But it follows logically from a worldview in which morality has no grounding beyond human consensus.
WHAT YOUR GUT ALREADY KNOWS
Here is where the argument lands:
If you read this and thought — even for a moment — “No. Even if every last survivor on Earth declared that genocide righteous, it would still be wrong” — then you already believe in objective morality. You believe some things are wrong regardless of what anyone decides.
That intuition is not an evolutionary accident. It is not cultural conditioning. It points to a moral standard that exists above and independent of human opinion.
That standard needs an author. A transcendent, personal moral lawgiver. What Christians call God.
The alternative — that morality is nothing more than majority vote — leads to a place almost no one is willing to go: a world where no atrocity is permanently wrong, because any atrocity can, in principle, be voted righteous.
You already know that’s not the world we live in. The moral argument for God’s existence simply asks you to follow that knowledge where it leads.
