What is Atheism?

[Neo-Scholastic]

I do believe many atheist have had experiences with the numinous. So we agree on that. The next step is to interpret that experience. Being an atheist necessarily entails other beliefs needed to exclude one particular interpretation of the evidence. You need reasons to prefer the set of explanations that exclude the divine.

Yes.

It's called "understanding the null hypothesis".

That depends on what the null hypothesis actually is? The idea behind a 'null hypothesis' is that proving one explanation requires disproving the current explanation. You are proposing without justification that God's absence should be the preferred explanation that must be disproved.

Anyways, let's see how that applies to an alternative proposition. I think it would very disingenuous for nearly any atheist to say he or she disagrees with the claim "The world is all that exists" which is functionally equivalent to lack of belief in God.
