I believe the Bible…but I've been trying to collect missing puzzle pieces elsewhere that would finally explain what happened in The Fall of Man. This new-age article ties in Samael and Lilith, explaining their connection to Satan: https://www.themystica.com/rape-of-eve: (even if not 100% correct does seem to connect some dots…)

• blood/menstrual blood occult / magick

• Garden of Eden deceptions

• line of Cain origin

• occult / alchemy

• Samael, Lilith, Djinn

…somewhat explains that "I, Pet Goat II" movie - the old lady in the phallic tower

See also: The Apocrypha

Nephilim + humans bore "gibborim"…sounds like they are also 'giants', but physically smaller.

Specific older texts (Greek and Hebrew) and the Apocrypha contain gems - puzzle pieces that will help fit the puzzle together.

And they were cannibals. Certain (((ones))) of them, anyway.

(pic comes from the book "Christianizing Homer: The Odyssey, Plato, and the Acts of Andrew..")

Wild random note: the Gibborim are, according to the Book of Enoch Chp 3, part of "song-uttering choirs" (!)…
