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.
Maybe a better question than what is "god" is what is "nothing" or somewhat strangely is nothing really something?
Can nothing be any more understood than the infinite?
