I have always enjoyed bringing in the "you know, the bible could be read very differently if you consider God to be an alien" to certain philosophical conversations I've had with people over the years, ever since reading von Daniken's work.
As you allude to, there are always other explanations.
There are documented cases where aliens weren't needed for that, either:
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.
