Ica Stones as Evidence of Ancient Extraterrestrial Civilization

RecordOBS-0472
CategoryExtraterrestrial/Ancient Aliens
StatusDEBUNKED
SummaryThe Ica stones are engraved andesite stones from Peru, some of which depict dinosaurs, advanced technology, and medical procedures. Proponents claim they are ancient artifacts proving that humans coexisted with dinosaurs and that an advanced, possibly extraterrestrial, civilization existed in the distant past. However, the stones are widely considered a hoax, with the creator admitting to forging them in the 1960s.
OriginThe modern Ica stones were popularized in the 1960s and 1970s in Ica Province, Peru, primarily by Dr. Javier Cabrera, who collected thousands of them. They were sold by local farmers, including Basilio Uschuya, who later confessed to carving them.
Claimed
  • The stones depict humans interacting with dinosaurs, suggesting humans and dinosaurs coexisted.
  • The stones show advanced medical procedures like brain transplants and open-heart surgery, indicating a highly advanced ancient civilization.
  • The stones are evidence of an ancient interstellar civilization that visited or inhabited Earth millions of years ago.
  • Some stones may be genuine pre-Columbian artifacts.
Evidence / consensusExperts and historians consider the Ica stones a hoax. The creator Basilio Uschuya admitted to carving them for profit, and the depictions include inaccuracies such as dinosaurs not native to South America and outdated anatomical features. Some stones without fantastical motifs might be genuine pre-Columbian artifacts, but the dinosaur and technology engravings are modern forgeries.
> OBSERVER NOTE:
A classic case of a manufactured mystery. The admission of forgery by the stone carver is the decisive fact, yet the myth persists in alternative-history circles. The stones are a testament to the power of confirmation bias.
