The disembodied spirits of the Raphaem... the Giants..

The Raphaem are of this world aren't they? The product of fallen angels and earthly women?

They are likely 2/3 divine, 1/3 human. See 1 Enoch and the Epic of Gilgamesh.

I know, my point is that they aren't extraterrestrial... they're from here. (more or less)

Inter-dimensional indeed.
