We wouldn't call that a scientific question. So, why would you think we would call, "Were humans created from Adam's rib?" a scientific question? What makes this worth investigating and not silly? Just because we don't have any other fully conclusive alternatives, doesn't make, "Were humans created from Adam's rib?" a scientific question.
You seem to be using "scientific" as an honorific term. And, at least in some contexts, it is. In some, of course, it isn't. The question is not worth investigation, I agree. But it is an empirical issue. If you feel it is too trivial, or silly a question to be called "scientific" that's fine. Call it an "empirical question".
