There’s so many other books they kept out of the Bible...
Because the people who assembled the Bible with all the scriptures thought these others like The Book of Enoch were some books people shouldn’t be reading due to containing truths.
They didn’t want to scare people away with when reading the Bible.
What made the Book of Enoch important enough to preserve but so controversial that it needed to be buried…? Abductions? ET encounters? Did "Watchers" fall from the Heavens?
Could they still be watching...
