Nephilim

The Nephilim appear briefly and enigmatically in Genesis 6:1–4, where the ‘sons of God’ take human wives and the Nephilim are ‘on the earth in those days,’ described as mighty men of old. The passage is terse and ambiguous. The fullest narrative comes from the Book of Enoch (1 Enoch), a Jewish work of the Second Temple period: there a group of two hundred angels called the Watchers descend on Mount Hermon, take human wives, father giant offspring, and teach forbidden arts such as metallurgy and sorcery. 1 Enoch was widely read in Second Temple Judaism and is quoted in the New Testament Epistle of Jude.

Ancient Aliens and other proponents of the ancient-astronaut hypothesis read the Watchers and Nephilim as a literal record of extraterrestrial contact: sky-beings who came down, mated with human women, and seeded humanity with technological knowledge — sometimes tied to the Mesopotamian Anunnaki and to claims of hybrid bloodlines.

Biblical scholars place these texts firmly in their religious-literary context. There are long-standing competing readings within tradition itself — the ‘angelic’ interpretation (fallen angels), the ‘Sethite’ interpretation (favored by Augustine), and a ‘dynastic rulers’ reading. The Enochic Watchers myth functions as an etiology of evil and of the Flood, drawing on wider ancient Near Eastern motifs; treating it as a transcript of an alien visitation imports a modern category that the authors did not have.
