I wrote in an earlier thread about what could possibly convince me of the existence of life after death, the supernatural and/or (a) god beyond reasonable doubt, and I came to the conclusion that it's just not possible. Everything I can think of has alternative hypotheses that are not in the realm of total impossibility.
I would like to pose a more general question: Is definitive and ultimate proof for the existence of God possible at all?
Many deluded believers, especially creationists, claim to have tons and tons of "proofs" (with which they really mean "evidence", as "proof" is something different completely) for the existence of God. Invariably these "proofs" are completely flawed.
So what would be credible proof? Is it even possible?
My pet alternative hypothesis (which isn't my invention, of course, as countless skeptics have also presented it way before me) is that of the Sufficiently Advanced Aliens using Sufficiently Advanced Technology (the one that's proverbially indistinguishable from magic). They can make it look like we are experiencing something supernatural, when in fact we aren't. Completely within the laws of this universe, but so advanced that it goes well beyond our understanding of it or, even more plausibly, just mass hypnosis. They could probably also affect any measurement devices we could ever have (or likewise, just hypnotize us to see results that aren't there). This for every possible "proof" or "evidence" that we could ever think of for the existence of a supernatural god.
Even if we had apparent "definitive proof" of a god, what could be more plausible, that it's really a supernatural entity, or that an alien species way beyond our technological progress is experimenting or toying with us?
What would convince you of the existence of a supernatural god?
