I hope this question doesn't offend anyone, but here goes: Are the sci-fi like parts of the Bible (Ezekiel's vison - Ezekiel 1:1–3:27 etc) considered on topic?
I think part of the problem is that, by claiming parts of it are "sci-fi", you are essentially saying "this is fictional". It would be a bit like asking if we can talk about the parts of Egyptian history that are "sci-fi like" like the pyramids.
That said, as Valorum commented in How do we differentiate between religion and fiction?, we really need to take things on a case-by-case basis. What sort of questions were you thinking of asking?
