What came first, the atheist or the theist?

[Autumnlicious]

When did I say that? I don't remember it :p

Given the very primitive reasoning involved in creating gods, I would say that it isn't so much that the first humans didn't believe in gods, it was that they simply did not have the cognitive abilities to wonder whether or not gods existed.

(my emphasis).

Absolutely correct. By default at the very beginning, a human has no concepts, not even of deities. Ground state, if you will.

So, by default, the atheist has to come first. As does a lack of knowledge. Hence why 99.99% of religious people have to be taught religion. In the first place. Or develop a little bit enough to mis-attribute a person-like entity to inanimate objects due to an incomplete paradigm and attribution of social cognitive abilities to a non-social object.
