In this illuminating lecture, acclaimed historical investigator Graham Hancock shares revelations from decades exploring Amazonia’s “pre-1492” mysteries. He believes ruins and artifacts hint at complex vanished civilizations, perhaps influenced by outside contact, challenging prevailing narratives of the remote region’s pre-colonial inhabitants.

Hancock describes anomalies like 6,000 year-old man-made earthworks and symbolic geoglyphs etched upon the forest floor that conventional science can’t explain from isolated tribal groups. He points to suggestive parallels between Amazonian and Mesoamerican mythologies and shared cultural items like psychoactive snuff kits as implying trans-oceanic interaction.

His on-site discovery of anachronistic metal chains and alleged evidence of coca crop domestication date back far earlier than accepted. Taken together, Hancock argues it signifies Amazonia was home to complex hierarchical civilizations we know little about prior to European contact.

Though controversially challenging orthodox frameworks, Hancock presents a persuasive case that the Amazon jungle still cradles secrets of pre-Colombian societies deserving deeper investigation. For any intrigued by mysterious lost histories, this talk explores a provocative theory backed by years of determined detective work.
