Proof of the existence of God set down on paper
Unlike other fools online, I'm humble enough to know not to argue with Godel. That said, I think there is a proof that God *does* exist: Multiverse theory. If one can prove that the Multiverse exists— an infinite number of universes with an infinite variety of physical laws— then by definition, God exists. Or, in practical terms, a God-like being exists that can exercise similar power over the creation, at least within "His" universe. Of course, if that's true, then that means that *this* universe, our universe, could have a God (again, defining God as a higher power). Alas, that doesn't prove that God exists in *our* universe, let alone that it's the God of Abraham (or Xenu, or the Norse, or etc., etc.).
