I don’t disagree that “something” preceded existence as we understand it, although I wonder what the implications of that are? I guess I’m more agnostic about anything that by definition can’t be comprehended.

I generally base my atheism as opposed to religious theism. If I were to roughly boil it down I’d say I don’t believe in any omnipotent entity that passes judgement on our existence.

Identifying as an atheist doesn’t mean you deny any possible definition of “God”, it’s referring to a specific definition or group of definitions that need to be agreed upon before any real conversation can happen.

Your argument would make perfect sense to anyone that agrees with your definition of “God” and also doesn’t believe in him. How large do you think that group is?
