What made the Book of Enoch important enough to preserve but so controversial that it needed to be buried……the scrolls date from the C3rd to the C1st BCE. The source of their narratives and their authorship remain a mystery.
With a worldview that says there is no such thing as an E.T. monotheising the canon of the Bible had to mean excluding these other narratives.
Why was the narrative of ET contact suppressed?…And are we entering a period where the veil of that secrecy is now being lifted?
