Nobel-winning author Doris Lessing wrote a novel called Shikasta in 1979 that (to my recollection) is a rewriting of the Old Testament and Earth history from the point of view of an alien community who played the role assigned to the divinities and angels in human myths.

I read it as a teenager and it really stuck with me as a completely different, more spiritually influenced take on science fiction and “ancient aliens” theories of the era. She won the Nobel Prize on the strength of her more autobiographical and feminist prose, so Shikasta is an outlier in her own body of work too.
