Nephilim: Origin of Genetic Evil explores human genetics, including elongated skulls, ancient "Nephilim Skulls" of giants, giant skull fragments, and Neanderthal skulls. It examines accounts of the Nephilim/Annunaki, ancient aliens/demons, fallen angels, and Satan—the father of all lies—from Hebrew, Babylonian-Sumerian, Egyptian texts, and the Book of Enoch. The film traces these narratives from underworld lore and Luciferian occultism to Biblical revelation and prophecy, including the words of Jesus Christ.
