Fact - the archeology of the Chalcolithic Age supports the introductions of technologies described in ths Book of Enoch as having happened at that time - predynastic egyptian eye painting started, writing started, new metal alloy production started, weapon production of maces and the like started, magic divination started, astrology started, sorcery started, terror started. All there is archaeology. All there in the Book of Enoch. All these truths about the Son of Man and God are there in this Book of Enoch and Jesus identified Himself as the Son of Man and the Dead Sea Scrolls include this Book of Enoch showing the Son of Man term was known from that book (quoted by brother of Jesus in a scriptural epistle - Jude).
