22. Nazca Lines
The Peruvian Nazca lines may not seem like much from the ground; however, from the air, they are a design that is nothing short of extraordinary. Archaeologists have determined the designs were made by the pre-Inca Nazca culture as a way to communicate with the Nazca deities. However, some theorists believe they were made for alien landings and ancient astrology. Regardless, you have to wonder how they could make such intricate designs from the ground and know that the end result would be this perfect.
