He created one universe. That's all he did onscreen. The STverse is bigger than that. And WTF do you mean "The universe where everything started"? OUR OBJECTIVE REALITY is the universe where everything, such as Star Trek, started. Morweh in Bruce Almighty is a fictional being whom we can only judge onscreen feats, not your subjective interpretation of what God really is.
Oh, we're going by the Bible then? Well in that case, again, Yahweh is a fictional being who we can only judge by screenfeats, because obviously, it is nonsensical to judge fictional characters on hyperbole and subjective interpretations.
