The book of Enoch details an era in humanity's past in which the evil grey aliens interbred with the native denizens of Earth (negros) and taught them how to write, cook food, wear makeup, and clothe themselves (read it if you don't believe me, it's all there). This essentially describes the "fall of Lucifer" from heaven and his impact on human evolution.

White people (and Asians, to an even greater extent) have vastly superior intellectual capabilities than the native Earth peoples. This is a result of the "Grey" or Luciferic DNA present in their genome.

They came here in an attempt to save their own race through genetic experimentation and hybridization. This is now common knowledge. They also use humans for food. The greys have enlarged brains and highly developed psychic abilities, and severely atrophied digestive systems. They actually grind up human glandular organs to create a kind of slurry which they absorb through their skin.

They have lost their connection to God, and retain no emotional or moral intelligence, only cold logic.

This is the kicker: The Greys used to be more like us. WE will evolve (or devolve, as it were) into THEM if we do not make the right decisions as a species.

I have more information if anyone has questions.
