That’s the problem with babies.
They may be born atheists, but they are also born not believing in the theory of evolution.

He’s joking but I actually like the line.
We are born without belief in God; that belief has to be drilled into us. If no one taught us what to believe, no doubt children would come with an explanation for how our world and the creatures inside of it came to be.
It’s our job to provide children with natural explanations so they don’t go chasing after the popular mythology their friends may buy into.
