Graham Hancock: Lost Civilization of the Ice Age & Ancient Human History | Lex Fridman Podcast #449

Graham Hancock lays out his hypothesis that an advanced seafaring civilization existed during the last Ice Age and was destroyed in the Younger Dryas cataclysm roughly 12,800 years ago. He uses Gobekli Tepe, the Giza pyramids and Sphinx, precession numbers in worldwide myth, and ancient maps as clues pointing to lost ancestral knowledge. He explains the Younger Dryas impact hypothesis involving the Taurid meteor stream and discusses why he believes the Sahara, the Amazon, and submerged continental shelves remain underexplored. The conversation also covers his feud with mainstream archaeology, his debate with Flint Dibble, and the role of shamanism and psychedelics like ayahuasca in the origins of human civilization and consciousness.

• Gobekli Tepe in Turkey is the oldest fully elaborated megalithic site known, dated to at least 11,600 years ago, making it about 5,500 years older than Malta's Gigantia, previously thought the oldest.
  00:11:25
• The Younger Dryas impact hypothesis, supported by more than 60 scientists across disciplines, proposes a cosmic impact event left a distinct boundary layer containing nanodiamonds, shocked quartz, and carbon microspherules worldwide around 12,800 years ago.
  00:39:42
• Hancock attributes the Younger Dryas to the Taurid meteor stream, debris from a large comet that entered the solar system around 20,000 years ago and broke apart, with Earth hit by hundreds of airbursts.
  00:44:23
• The three Giza pyramids match the pattern of Orion's Belt, and the Sphinx aligns to the rising sun on the spring equinox, locking perfectly to a date of around 10,500 BC during the Younger Dryas.
  00:58:59
• Robert Schoch's geological analysis of water erosion on the Sphinx suggests it dates back to around 12,500 years ago, far older than the standard attribution to the Pharaoh Khafre.
  00:55:54
• Hancock argues the lost civilization should be sought in places hospitable during the Ice Age but barely studied: the then-fertile Sahara, the Amazon rainforest, and submerged continental shelves.
  01:16:18
• Hancock proposes that shamanism is the origin of human civilization, with shamans acting as the earliest scientists through plant experimentation, and psychedelics like ayahuasca switching on the modern human mind.
  01:56:50

• The Indus Valley civilization was itself a lost civilization until the 1920s, when railway workers accidentally stumbled across ruins, and a 5,000-year-old seal depicts a figure in an advanced yoga posture.
  00:05:43
• Gobekli Tepe was deliberately decommissioned, buried under earth and rubble, and topped with a hill; 'Gobekli Tepe' means potbelly hill or hill of the navel.
  00:14:02
• The precession of the equinoxes is a roughly 25,920-year cycle, moving one degree every 72 years, about the width of a finger held against the horizon in one lifetime.
  00:29:41
• The precessional number 72 and related numbers like 108, 54, and 432,000 recur in mythology worldwide, including 72 conspirators who killed Osiris and 54 figures on each side of the bridge at Angkor.
  00:30:44
• The 1908 Tunguska airburst in Siberia destroyed 2,000 square miles of forest and occurred on June 30, during one of the two annual passages through the Taurid meteor stream.
  00:46:30
• The Great Pyramid is a roughly 6-million-ton structure with sides about 750 feet long, aligned to true north within a 60th of a single degree, with internal passages sloping at 26 degrees and exterior at 52 degrees.
  01:07:24
• Hancock found that Flint Dibble's claim of 3 million mapped shipwrecks was actually a UNESCO estimate, with the real figure closer to 250,000, most from the last thousand years.
  01:34:32
• The peopling of Australia around 50,000 years ago required an ocean voyage of 90 to 100 km across open water, and the settlement of Cyprus involved planned migrations of over a thousand people at a time.
  01:36:04
• Ayahuasca works because DMT-containing leaves are combined with the ayahuasca vine, which contains a monoamine oxidase inhibitor that prevents the gut enzyme from shutting down orally absorbed DMT.
  02:00:28
• Researchers at Imperial College London and UC San Diego use a DMTX drip technique to keep volunteers in a peak DMT state for hours, with subjects consistently reporting encounters with sentient others teaching moral lessons.
