The Nazca Lines, Peru
The Nazca Lines are a well-visited site by Sci-Fi fans and extraterrestrial aficionados. However, it’s difficult to explain why the prehistoric Nazca culture created the enormous geoglyphs in 500 BC, depicting an array of spiders, monkeys, figures, and flora. Many theorize that their creation was part of a ritual or out of the belief that the glyphs linked up to constellations in the sky.
