Puma Punku Lost Technology

Record	OBS-0660
Category	Extraterrestrial/Ancient Aliens
Status	DEBUNKED
Summary	This theory claims that Puma Punku's stonework exhibits machine-like precision, including perfect right angles, drill holes, and interlocking H-blocks, which proponents argue could not have been achieved by the Tiwanaku civilization with simple tools. They suggest the site may be evidence of a lost advanced civilization or even extraterrestrial influence. Mainstream archaeology attributes the construction to the Tiwanaku culture using stone tools and ramps, and notes that the precision is often exaggerated.
Origin	The mystery of Puma Punku has been popularized in alternative history circles since the 20th century, with renewed interest in the 21st century through books, documentaries, and online articles.
Claimed	The stone blocks at Puma Punku are cut with laser-like precision, comparable to modern CNC machining. The H-blocks are standardized and mass-produced, suggesting advanced manufacturing. The site's high altitude and lack of trees make conventional transport methods impossible. The Tiwanaku civilization lacked the technology to create such structures, implying a lost or extraterrestrial origin.
Evidence / consensus	Archaeologists and engineers have shown that the precision can be achieved with stone tools and careful measurement. The claims of impossibility are exaggerated; the Tiwanaku were skilled stonemasons. No evidence of advanced or extraterrestrial technology exists.

> OBSERVER NOTE:
The 'lost technology' narrative is a classic trope in alternative history. The site is impressive but not anomalous. Claims of impossible precision are often based on selective observation and ignore the variability in the stonework.
