That isn't how I, or any atheists I know, define atheism.
I was digging at the idea that someone would accept a claim on Faith, then demand evidence before giving up the idea, and how that is inconsistent. If someone can faith into an idea without evidence it should be equally easy to faith out of it with no evidence.
That it's not easy, is interesting.
Nothing -> belief in God, costs little and gains much.
Belief in God -> no belief, costs much and gains little.
Where by costs and gains, I include social acceptance, eternal life, favourable relations with a powerful being, forgiveness of sins, approved life habits, connections to history and social groups, etc.
It's not a Boolean. Or at least, from inside a mind it doesn't feel like a Boolean.
edit: I would also like to add, although I already said it, that I believe both of these opinions regarding the creator are acts of faith, to absolutely say there is not one and to absolutely say there is, and if someone where to have made a statement as if a creators existence was a sure thing I would have called them out just the same.
