@geoffc :-) If I would be some religous-like ufo believer, I still could ask what I want. Of course it should be well-packed, but I could ask. For example, Skeptics SE does not work on this way: they detect a true reason (or a reason what they think as true reason), and if they dislike it, then they close-down-del the question with a fake close reason.
Space SE would never do this deepness, imho.
For example, a question like "Are the extraterrestrials among us?" would be closed, but a question targeting the paradox of that on our estimated technological development predicition, they should have long (possibly billion years ago) reach us, that could have a good chance
