Of course, the question arises at the next universe up, at the next level up: Who created them? Did someone create the whole system of universes? And I see no particular reason to think so. Maybe if you wanted the genuine traditional god, you’d need someone who created the whole multiverse rather than just a local god who created this local universe. As far as I can tell there’s no particular reason to think there has to be some god responsible for creating the whole multiverse. The chances are the god that you’re going to get from this simulation theology is an extremely watered-down god that would probably seem somewhat blasphemous from the perspective of traditional religion.
