You're making a hell of a lot of assumptions. There's no evidence of a creator, no evidence the creator is a "He" and no evidence that it is remotely human with human concerns and that it cares about what we do one way or the other, or that it has any involvement after creation. You're projecting a creator that looks and thinks like you with absolutely zero evidence, which is alternatively your own lack of imagination or too much imagination depending on how you slice it. And we can go around and around on this argument, which after 50 years on this planet I can reassure you that I've seen it before. Even if I grant you a Creator (which I don't, we can always assume an infinite multiverse instead or just that cosmology allows for a causeless effect) then there's nothing that falls out of that other than the existence of a Creator. You then wind up with something like Spinoza/Einstein's God or the Prime Mover that agnostics like to consider. There's no evidence of any of it though.

It doesn't "fall apart", it just doesn't have any answer for what came before it.

That doesn't disprove what it can prove. We know the universe used to be very hot and dense and expanded and cooled.

What I don't buy is that because we don't understand something -- like what came before the big bang -- that it necessarily implies the existence of some old white bearded cishet white male who cares about our day to day lives.

I'm perfectly happy with having absolute uncertainty about what came before the big bang. There doesn't need to be any explanation, and there certainly doesn't need to be a religious explanation.
