The Book of Enoch and the Book of Giants imply that these Watchers tampered with the natural order of God’s creation. According to Enoch 7:5, and that’s the real 1st Enoch, not the fake 2nd and 3rd books, the Watchers taught humanity how to mix species and experiment with life forms, resulting in monstrous beings and hybrid creatures. This genetic corruption involved blending humans, animals, birds, and reptiles, which defiled the original creation and contributed to the rampant evil before the flood.
The Book of Giants particularly emphasizes how this genetic manipulation spiraled out of control, leading to the creation of enormous, grotesque beings who caused devastation on Earth. This hybridization and genetic engineering were key reasons for the flood, as God sought to purify the world from this corrupted state.
The Nephilim themselves begin to realize their impending doom through visions and dreams. They see the consequences of their genetic manipulation and fear the judgment that is coming. Some versions of the text detail their attempts to petition God through Enoch, but their efforts are in vain, leading to their ultimate destruction.
These stories suggest that pre-flood genetic engineering was a significant aspect of the corruption in the ancient world. The fallen angels introduced forbidden technologies and knowledge, leading to widespread moral decay and the creation of abominations. I’ve heard of the Dinosaurs being created to serve as mules for the Nephilim. This ties into the broader narrative of a world that had become so defiled that only a cataclysmic event like the flood could cleanse it.
The genetic engineering in these ancient texts reflects a world where divine beings tampered with God’s creation, producing unnatural hybrids and contributing to the moral collapse that led to the flood.
