This may actually be possible...

[Darwinian]

What if we are all just AI in a super complex videogame? And what if Jesus, and all the other "magical "people were players? Maybe using a glitch to levitate on water? I'm certain that this isn't true, but if it was, there's really no way we would know.

This is entirely possible and yes, we would have absolutely no way of knowing either one way or the other. It's equally possible that the universe in which this one is being simulated is in fact a simulation itself as well from an even more complex technology, perhaps in a universe where the laws of physics are sufficiently different to allow this sort of thing to happen.

But, unless someone knows different then we can never know and so the subject is firmly wedged in the realm of philosophy and the best thing to do is to say, hang the sense of it all and just keep yourself occupied
