I ' m not saying that a god can ' t exist , I ' m saying that it can ' t be omnipotent within our universe . It can be 99 . 9999999 . % omnipotent , but there are a few things that it could never do . Also , I don ' t necessarily equate god with omnipotence . I like the Norse view where gods were merely super powerful beings rather than these incomprehensible concepts of infinity . nbspAs for there being constraints in other universes , I ' m using using a sort of topdown logic . If said universe exists , there are some rules and constraints that happen to exist for that universe , even if they exist as some concept of infinity that we can ' t comprehend . It ' s that they just happen to be rather than be chosen or set with conventional logic . I ' m not sure if that makes sense , but I don ' t know how to explain it with better words .
