I disagree on it being one true bloodline, though those that are doing what they’re doing certainly see it that way, and they def see themselves as superior (are are their cattle in their eyes)

And yes the beings are referenced in the bible heavily. Also almost every other human civilization on Earth, regardless of how separated by time or distance, makes reference to beings that came either from the skies or the waters, taught them astrology, agriculture, timekeeping etc. The nommo/chitauri of the Zulus, Quetzalcoatl and others from Aztec stories, Cherokee’s Moon eyes people, the Wanjina of the Australian Aborigines, the Hindu Veda’s makes reference to them along with flying crafts. Etc literally goes on and on. Most people alive today are not ready to receive this information currently, much to their misfortune.
