It makes no sense to ask where the universe came from.
Why?
Because it is not possible nor will it ever be possible to say anything about what was before the big bang. The universe as we know it, space, time and matter is a result of the big bang and talking about what was before is futile.
And introducing a god into the whole shebang makes it infinitely more complex. Where did god come from, who created god etc. By doing so, you introduce a whole new layer of problems that can not be answered, so the easiest part (Occams razor) is to remove god from the whole deal as it is not necessary.
Who? more like how...
