If something is in principle, by definition, *unknowable*, then it seems to be in principle, by definition, *nonexistent*; is there a term for this thing?
This is why there is no real difference between agnosticism and atheism. If God is really unknowable as the agnostics claim, then he is basically non-existent as atheists claim. But if he has revealed himself in time and space, as most religions claim, then he does exist.
While I do think there's not really a meaningful difference between atheists and agnostics, I also meant something different in my original tweet that I'm realizing now I should explain in more, better words
