Puma Punku built by ancient advanced technology

Record	OBS-0169
Category	Extraterrestrial/Ancient Aliens
Status	DEBUNKED
Summary	Proponents claim that the precision stonework at Puma Punku, Bolivia, could not have been achieved by the Tiwanaku culture using simple tools, and suggest it was created by an unknown advanced civilization or with machine tools. They point to the extreme flatness of surfaces and the massive size of the blocks as evidence.
Origin	Modern fringe theories, popularized by authors like Brien Foerster and others in the ancient aliens movement, particularly in the 2000s and 2010s.
Claimed	The stone cutting precision at Puma Punku is beyond what primitive cultures could achieve. The blocks were cut with machine tools, not hand tools. The site may have been built by an advanced ancient civilization or extraterrestrial influence. The stones were moved from distant quarries using unknown methods.
Evidence / consensus	Archaeologists and materials scientists have shown that the Tiwanaku culture had the necessary skills and tools to shape and move these stones, and the precision can be achieved with careful stoneworking techniques. The geopolymer theory suggests some blocks were cast, not carved.

> OBSERVER NOTE:
Another case of attributing remarkable ancient craftsmanship to aliens or lost tech. The evidence points to human ingenuity, not extraterrestrial intervention.
