The author of Bloodline of the Gods explores the theory that ancient aliens shared the secrets of immortality with Old Testament figures.   While scientists debate the theoretical possibility of immortality, it may have already been achieved in the distant past. History is filled with accounts of fantastic beings, powerful gods, and half-human/half-alien entities that had extraordinarily long lifespans. Today, these stories are dismissed as mere folklore and mythology. But what if the accounts are all too real?   In Immortality of the Gods, Nick Redfern considers the possibility that ancient aliens uncovered the secret to stopping the aging process. Examining the legends of the Anunnaki, Redfern investigates how these ancient deities may have achieved everlasting life, and why they might have shared their secrets with Noah, Methuselah, and other biblical figures.   Redfern goes on to explore the saga of Gilgamesh, a long-lived part-human, part-extraterrestrial Sumerian ruler obsessed with immortality. Also in this volume, Redfern studies the claim that an undisclosed motivation for the 2003 invasion of Iraq was to uncover the millennia-old secrets of white powder gold, a manna-like substance that supposedly rejuvenates cells and tissue.
