I have to say I find the responses in this thread somewhat perplexing and dissapointing. You make atheists look like hard headed idiots who are not interested in proof but only interested in confirming their non-belief.
Now the most reasonable reaction to singularly hearing a voice claiming itself to be the voice of God is assume a hallucination, that’s true. It may be possibly actually be the voice of God, but more likely it is a hallucination or some sort of trick.
Now - everyone in the world unamimously confirming the experience - this makes it far less likely to be a delusion, since there’s no plausible way for everyone to spontaneously share such a delusion at the same time. There become other possibilities like some sort of advanced mind control technology or aliens - or, I guess, you could suppose a completely looney tunes hallucination where you’re just completely off the rocker at that point and envisioning newcasts in which it’s declared that everyone in the world had this experience, and that everyone you meet confirms it. But now all explanations are so unlikely that it actually being the voice of god is much less unlikely.
In the third case - if suddenly every hardcore Christian on the planet were taken away, that would be fairly compelling evidence. Sure, maybe they all went into hiding, maybe aliens scooped them all up as a practical joke - but by now, especially if you combine these events, a pretty good case can be made for believing in god.
Sure, it may be one of those far out explanations that’s the case - and the issue should be investigated by that time - but at this point it starts becoming quite reasonable for an atheist and a skeptic to start believing in god. Those things, while having other explanations, still constitute evidence.
The attitude in this thread actually isn’t skeptical at all. It’s not skeptical to say “no matter what, I don’t believe it” - skepticism is the philosophy of requiring evidence to support positions. This would be evidence.
For the hand of god to scoop you up into the sky, and then, say, create a mountain in the middle of a flat plain, and tell you “Hey, God here, you should believe in me - and oh in case you think you’re just hallucinating, check out CNN when you get home, they’ll confirm everything happened” and then you say “WELL NO THAT’S JUST SILLY! GOD DOESN’T EXIST!” in response to it is not skeptical, a weird idiotic denialist position.
And if you see a giant flying pink unicorn flying all over the world, and everyone else sees it, and thousands of cameras record the image, and people running radar systems across the world confirm something is really there, what’s the point of saying “flying unicorns don’t exist!”?
By taking on this attitude, you actually empower religious people. When they say stuff like “oh it’s not that you lack proof, you’re just unwilling to admit god/see the light”, this sort of thread confirms that very thing. You actually undermine the atheist position as the most rational, supported position to one to a denialist position where you’d feel that way no matter what evidence/arguments/proof.
You have to be open to the possibility of the existance of god to rationally conclude that it’s almost certainly not true.
This sort of hypothetical is extremely unlikely to ever happen - and that’s sort of the point, god is extremely unlikely to exist - but in the hypothetical that there was pretty good evidence of something pointing to god’s existance, the hypothetical reaction should be to very well consider the possibility of God’s existance.
