Generally speaking it rests on “god” or “gods” being beyond our comprehension. The whole “biblically accurate angel” thing isn’t just a meme, it’s best effort attempts at making images of something described in a way that most people nowadays would consider borderline lovecraftian.

So it kinda follows that if those things are supposed to be the approachable messengers, than anything remotely human-like can’t map well to “form” of the god over them.

Biblically there’s already arguments for time not being a thing for the Christian god. If omniscience is truly what it says on the tin, there’s no reason that a being with it couldn’t care about what every creature in the universe is doing with their respective reproductive bits.
