Probably the most famous weird thing in Peru is The Palpa Flat Mountain which many people have speculated was some kind of landing pad for aliens. The mountain is huge and the surface is perfectly flat almost like it was cut with a laser or something...
Then just a few miles away from the 'Alien petrol station' are The Nazca Lines. They are like the worlds first crop circles except they stretch for up to 15 miles in some cases, but remain perfectly straight the entire way across.
Could these be the work of Aliens?
