alien art?

摘要

IF YOU FLY OVER THE DESERT on the southern coast of Peru, you'll spot dozens of line drawings, stretching hundreds of feet across the arid landscape. The Nazca people created these images-depicting such characters as a whale, a hummingbird, and an astronaut-esque man-nearly 2,000 years ago. The etchings may have served as a massive astronomical calendar or offered tribute to the gods, though their actual purpose still eludes historians. While some suspect alien interference, the methods the Nazca used probably aren't quite so far-fetched.
