Tiwanaku as an Extraterrestrial Construction

Record	OBS-0661
Category	Extraterrestrial/Ancient Aliens
Status	DEBUNKED
Summary	Some fringe theorists claim that the ancient site of Tiwanaku in Bolivia was built by extraterrestrial beings due to its massive stone blocks, precise mortarless joints, and advanced engineering. They argue that the technology required for such construction was beyond the capabilities of the indigenous cultures of the time. Mainstream archaeology attributes the site to the Tiwanaku culture, with evidence of human engineering and transport methods.
Origin	The theory gained popularity in the 20th century, particularly with the rise of ancient astronaut literature, though the site's mysteries have been discussed since the Spanish conquest.
Claimed	The precision of the stone joints at Tiwanaku is so perfect that it could only have been achieved with extraterrestrial technology. The massive stone blocks, some weighing up to 130 tons, were transported over long distances using methods unknown to ancient humans. The site's alignment and construction suggest advanced knowledge that predates known human capabilities.
Evidence / consensus	Archaeologists and historians attribute Tiwanaku's construction to the Tiwanaku culture, with evidence of human labor, engineering techniques, and local quarrying. The transport of stones is explained by known methods such as ramps, logs, and reed rafts.

> OBSERVER NOTE:
Another ancient site claimed by ancient astronaut theorists. The evidence for human construction is solid, but the allure of mystery persists.
