Chaco Canyon

What the Show Claims

• ›Great Houses aligned precisely to solar and lunar cycles — impossible without alien knowledge
• ›A road system extends 400 miles in perfectly straight lines — built for alien vehicles, not foot traffic
• ›The site was mysteriously abandoned c. 1150 AD — the inhabitants may have been taken by alien visitors
• ›Petroglyphs in the canyon depict alien beings and spacecraft

What Archaeology Says

Chaco Canyon was the ceremonial and political center of the Ancestral Puebloan world from c. 850–1150 AD. The Great Houses are precisely aligned to solar and lunar cycles — evidence of sophisticated indigenous astronomical knowledge. The road system, while remarkable, served ceremonial and logistical purposes for foot traffic and goods. Chaco's decline correlates with a severe 50-year drought beginning around 1130 AD, documented in tree ring records.
