Graham Hancock

British author and journalist whose research argues for the existence of an advanced antediluvian civilization destroyed approximately 12,800 years ago by the Younger Dryas impact event. His work connects megalithic construction worldwide — Egypt, Gobekli Tepe, Easter Island, Angkor Wat, the Americas — to a single source civilization that seeded advanced knowledge across the globe before being wiped out by catastrophe. His Netflix series 'Ancient Apocalypse' became one of the most watched documentaries on the platform despite fierce backlash from mainstream archaeology. Hancock's framework doesn't require aliens — he argues for a lost human civilization — but the mathematical precision of megalithic sites (Great Pyramid encoding pi and the golden ratio, sites aligned to stellar positions, base-12 mathematical systems appearing globally) connects directly to the sacred geometry, cymatics, and Sumerian knowledge threads. Whether the builders were human, non-human, or human-taught-by-non-human, the engineering and mathematical knowledge is real and unexplained by conventional archaeology.
