I mean does it matter really? The Book of Baruch says the nephilim perished in the flood of their "own" ignorance. That means reguardless of their DNA they made their own choice within this free will physical dimension. After much thought, I believe if any entity has human dna they are given the same chance as any other man. Monkey, serpent? Is not everything made of the exact same elements? Animate and inanimate? Someone had made a point how blood was just as an illusion as skin color. You know what? It is an illusion but just as real as anything else here 3D.
