This investigation started as a statistical test of the claim that Giza, Nazca, Easter Island, and other ancient sites fall along a single great circle. The final results are now published and both papers submitted.
The alignment is real. That's confirmed across 8 independent databases totaling 550,000+ sites. Monuments cluster at 5x expected while settlements in the same regions don't.
But the explanation is a five-layer causal chain, not a mystery: plate tectonics aligns the geological features (0.8° from the Alison pole), geography produces the divergence (ML decomposition — the Great Circle adds zero predictive power), the desert belt concentrates the signal (93rd percentile for 30th parallel), Easter Island is the only inhabited Pacific island within 200 km, and the sub-km precision is a 1-in-3,000 coincidence.
The lost civilization hypothesis was tested with 94,181 radiocarbon dates spanning 25,000 years. The corridor — spanning Peru, Egypt, Iran, South Asia, and Southeast Asia — was emptier than average before the Younger Dryas. Every proposed Atlantis location is either on abyssal plain or has zero archaeological coverage.
