The idea of atheism had to come from somewhere

You have it the wrong way. The idea of religion came from somewhere. Atheism is the default you're born with, although most people have a propensity towards wanting eternal life and concrete answers to all questions of the unknown, which religion provides.

Atheism is the default you're born with Atheism is too sophisticated an idea for this to be the case. It requires that one have an idea of God to deny. Epicurius, for instance, must have had the Olympian Gods to deny and then Plato's idea. There are plenty of practical atheists, but few formal ones, and most lazily call themselves agnostics.

Atheism is the default you're born with

..until you look around. The fool--and perhaps children--say in their heart there is no God.

Atheism is the default you're born with

Atheism is not the default that you're born with. Atheism is a belief, and it hasn't been proven that babies are born with either a belief in the existence of God or a belief in the non-existence of God.

I disagree. God is the default we are born with...atheism is the idea humans came up with when they decided they wanted to run their own universe.
