I think it's pretty natural to assume that the creator of a universe started outside the universe. After all, before the universe existed, how could a God be inside of it?
If you don't think the God in question created the Universe, then any number of other options apply. But, if one (and again, I don't) think a Creator or a God created the Universe, it seems implied that he is outside of the Universe, at least at the beginning.
Of course, that doesn't answer the question of where God came from, but whatever the answer to that is doesn't mean he must follow the Universe's laws.
