Who is God?

Nothing because it doesn't exist.

I think given the OP and the subforum, the question is pretty clearly asking what "God" is if one exists ... but thanks for your input in the form of a definitive statement about something you quite literally cannot know for sure, haha.

I personally think God is really Nature itself...

I think labels like "Pantheism" or whatever have really messed up how people think about this (admittedly broad) idea, because classical Christian ideas of God are of an immaterial consciousness that is eternal and outside of space/time.  Saying "God is nature" would probably piss off more (especially conservative) Christians than it should, because God would certainly be closer to being "nature" (at least in some sense) than He would be to being something like Zeus.

If anything, God could even somewhat be accurately described as math itself ... in that math would be the "mind of God," and God is classically understood to ONLY be a mind.

A fairytale

I wish I could disagree with you, because part of me wants there to be something more than just this. But I can't honestly convince myself that that is the case.

I find the idea that nothing collided with nothing to create something, and the Universe created itself, to be just as difficult to believe than a hypothetical entity that exists outside of the natural Universe and acted as its first cause.
