The Basement: Cassie Coppersmith | Ancient Technology was More Advanced Than We Think
The Why FilesNov 9, 2026
Former gold mine dealer Cassie Coppersmith joins AJ Gentile of The Why Files to argue that ancient builders had technology far more advanced than mainstream history acknowledges. She discusses LiDAR scans beneath Cambodia's Angkor that revealed geometric mound fields, mile-long spirals, and a water network that seems to work like a machine, and she claims carbon dates there don't match the official timeline. The conversation also covers lathe-turned stone pillars in India, the Moai along Easter Island's ancient road, megaliths in Ethiopia, and a strange knocking she heard one night inside the world's largest cave.
