Did Aliens Build the Olmec 17 Heads? | Luke Caverns

Julian Dorey interviews independent history creator Luke Caverns on episodes of early American and Mesoamerican history, before shifting into speculative questions about ancient engineering and belief. Caverns describes the hazards of wagon travel across the Great Plains and makes a dramatic claim about the Comanche’s ability to plan attacks over large distances, referencing S.C. Gwynne’s work. The conversation then turns to the Spanish arrival in Mexico: Caverns sketches a timeline for Hernán Cortés’s march inland and recounts contested claims about whether the Aztecs viewed the Spaniards as divine, linking it to the Quetzalcoatl prophecy.

On epidemic disease, Caverns argues that stories of clergy distributing “smallpox blankets” are often interpreted as deliberate biological warfare, but says intent is unclear and suggests some priests may have acted without understanding contagion. The pair then discuss Amazon archaeology, including terra preta soils and the risk of clickbait narratives that portray the rainforest as “man-made”, which they argue could weaken public support for conservation.

In the episode’s central “mystery”, Caverns outlines the Olmec civilisation’s early rise near the Coatzacoalcos River and says the culture produced colossal basalt heads seemingly from the beginning of its urban development. He cites a nautical engineer’s modelling exercise that, he says, fails to explain how multi-ton heads could be rafted upriver. The closing section broadens into aliens, religion, and consciousness: Caverns floats “psychedelic archaeology” as a way to better understand ancient ritual and astronomical architecture, drawing on his own experiences with cannabis edibles and stargazing.

• Caverns questions the reliability of claims that Indigenous peoples saw the first Spaniards as “gods”, saying the evidence is mixed.
• He argues intent behind alleged “smallpox blankets” is uncertain, citing the lack of germ theory at the time.
• The pair discuss terra preta and reject a simplified “Amazon was a man-made garden” narrative, warning of clickbait effects.
• Caverns places the Olmec origins around San Lorenzo and describes rapid early monument-building, including colossal stone heads.
• He says an engineer’s modelling suggests raft transport of the heads on the Coatzacoalcos River is mechanically problematic.
• Caverns proposes “psychedelic archaeology” as a lens for interpreting shamanism, religion, and ancient sky-aligned architecture.
