There Were Giants Upon the Earth by Zecharia Sitchin explores the theory that the Anunnaki, an advanced race from Nibiru, genetically engineered human ancestors.

: The assertion that humanity’s evolution was jump-started by extraterrestrial genetics. The Anunnaki Legacy

: An exploration of how these beings established early civilizations and established kingship as a way to govern humans. Decoding Longevity
