Oh, then indeed I'm presupposing theistic religion as the target of atheism. Once the theistic conception of God dissolves because of its incoherence, there's nothing left for the atheist to refute.

I infer, then, that atheism wins by default, whereas you want to say deism is another option. Deism presupposes God as a law-giver, though, maintaining just that there's no supernatural revelation and that God doesn't intervene in the operation of those laws.

I think maybe you'd want to posit, rather, a mystical conception of God, one in which God isn't a person. That would make for a contrast with theism, but the contrast would be so strong, I maintain, that it would be consistent with atheism. So once again, the atheist is the only one left standing.
