Saying:
"You can't prove God exists, so God doesn't exist"
Isn't the same as saying:
"You can't prove God exists, so I'm reserving judgement until you or someone wlse does, or until I die."
Your reasoning - the first statement - doesn't apply to me (or to anyone with a brain, in fact).
And yet: I don't believe.
So: you're wrong.
That first statement isn't, contrary to your OP, "necessary" for not believing. Is it?
So: you're wrong.
Yeah, but THIS POST DOES NOT APPLY TO YOU, this post applies to people who disbelieve in God, you neither believe nor disbelieve but reserve judgement
So I win, I'm right, you're wrong
