It doesn't make any god damn sense.
Most religions and science seem to agree on one thing, there was nothing in the universe and then there was something after some deity/phenomenon created everything, but now we're gonna get into the meme "who created god" question.
Really though, think about it, just about every explanation humans have come up with over the millennia for how the universe came into being always implies that there was something "before the universe," inadvertently science and religion both agree that you can't make something from nothing (even if it's an unintentional implication) and there some something before this """nothing"""
Now, this is the point I realize we get into an endless question loop, what came before that "something?" We've established that you need something to make something, so something had to exist before the deities/phenomenon that created our universe, but the question isn't what it was so much as what came before even that, and before that, etc... We can ask this question a million times over and again and again the same question comes up unless we get into a legitimate state of nothingness, but then we have to throw away our whole "you can't make something out of nothing" principle that it seems everyone agrees on.
It's like some kind of impossible question where the point is that you're supposed to eventually figure out it's impossible and you've just been put through a loop, but here we all are so obviously it isn't actually impossible.
