From Pliny the Elder’s burning shield to a Renaissance Madonna with a disc in the sky, the idea that aliens visited antiquity has deep roots in modern pop culture. This episode traces the ancient astronaut hypothesis from 1898 science fiction and H.P. Lovecraft through Italy’s clipeology movement, Carl Sagan’s misread 1966 caveat, and Erich von Daniken’s 1968 bestseller Chariots of the Gods.

We examine the evidence proponents cite and what mainstream scholarship says instead: the Watchers and Nephilim in Genesis and Enoch, Ezekiel’s wheels, the cargo cult model, Wandjina rock art, Pakal’s sarcophagus, lenticular clouds in Renaissance paintings, and the out-of-place artifact argument for the pyramids, Stonehenge, the Nazca lines, and the Easter Island moai. The episode also covers Zecharia Sitchin’s Anunnaki claims, Akhenaten’s elongated skull, and the sociological fight over whether the theory strips indigenous cultures of their achievements or, as Ruth Burns argues, whether dismissing star-people traditions is its own form of erasure.

• How Sagan and Shklovsky’s cautious possibility became von Daniken’s certainty during the space race
• Why Pakal’s tomb carving shows the Maya world tree, not a rocket
• Merer’s papyrus logbook, the step pyramid of Djoser, and the Bent Pyramid as proof of gradual engineering
• Pavel Pavel walking a moai with 16 people and Joe Nickell recreating a Nazca figure with stakes and string
• Sumerian bilingual dictionaries that contradict Sitchin, and Marfan syndrome as an explanation for Akhenaten
