Yeah, this is a tough one, too. Since no evidence exists for alternative universes, either preceding or parallel, these things cannot be tested. Just because a parent universe could exist doesn't mean it did exist. The only evidence available is that the universe we live in is the only universe that does or has ever existed. So when ordering possibilities, the parent universe and a lineage of universes falls lower in likelihood than the current universe is the only one, ever.
