It always puzzles me when people ask 'what caused the universe?'.
When I think of the universe, I think 'everything that exists'. Obviously, we don't quite know what this comprises of, and some people think it includes gods and some don't, and some people think it includes branes and strings and extra dimensions, and lots more don't.
But we can still label it, and the word I'm going to use for that is 'universe'.
So what could cause the universe? Ignoring the fact that spacetime is a part of the universe (and so 'cause' really ceases to mean something when you ask what caused time itself), I'm unclear how an answer to this question could be formed.
Let's say you tell me what caused the universe. Okay.
And let's also say that the universe cannot have caused itself. People tend to object to things like that.
So now we have two possibilities. Either this thing that caused the universe is in the universe (which cannot be, as that would be the universe causing itself), or it is not in the universe (which cannot be, as by definition the universe means 'everything').
This doesn't rule out a god creating stars and galaxies and planets and whatnot. But it does rule out a 'cause of everything'. It simply cannot exist (unless the 'cause of everything' is everything (or part of it) itself).
