Caveman babies who can't sit up.

Fascinating new studies at the Infant Cognition Center at Yale University have demonstrated that children as young as 9 months old make moral judgments, exhibit bias, and have a sense of justice. Think about that from a naturalistic perspective. It is no surprise to the Christian worldview that some sense of good and evil is written on our hearts and in our minds. Hebrew 10:16 explains it. But naturalism is hard-pressed to explain how a moral code exists in DNA and packs of neurons and why morality might have evolved in caveman babies who couldn’t even sit up.
