The Basement: Cassie Coppersmith | Ancient Technology was More Advanced Than We Think

Summary

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.

Key takeaways

• 1LiDAR scans around Angkor, Cambodia reportedly revealed geometric mound fields, mile-long spiral structures, and a hydraulic water network described as behaving like a machine
• 2Coppersmith claims Cambodia's finest stonework sits at the lowest, oldest layers of sites, suggesting a decline in building skill over time rather than progress
• 3She asserts carbon dates at Angkor-area sites conflict with the official construction timeline
• 4Stone pillars in India are presented as evidence of ancient lathe-turning and spindle technology applied to granite
• 5Easter Island Moai are discussed as lining an ancient road, fitting a recurring global megalithic pattern
• 6Coppersmith describes hearing unexplained knocking in the dark while camping in the world's largest cave (Hang Son Doong, Vietnam); she also mentions megalith sites in Ethiopia
