I will talk about the Nazca lines in Peru. First, The desert of Nazca is a place ubicated in southern Peru. In this desert there are a series of lines who makes a interesant draws like geoglyphs. This lines were created by Nazca culture, and how they did it is a mystery. There are drawings from simple geometric figures to complicated drawings like birds or monkeys.
The lines were made in a desert. thus have been preserved until today. The lines have a similar conspiracy of the pyramids: Aliens. Is said that, as with the pyramids, is the work of aliens. But they are just theories. Likewise, experts say, that the lines were possibly made using thousands of strings to calculate the dimensions of the drawings to make straight lines. The lines have no more than 30 cm deep. Texture that is due to a projection at the edges of the lines. Almost all the drawings were made on the flat surface. There are only a few in the hills. Almost all the figures that are in the hills are men.
Over thirty geoglyphs found in Nazca until today. There are fewer drawings in the desert compared with designs that are needed to make one. The construction technique was careful enough to be carried hills and ravines without deviating from its original direction. The draws were discovered relatively recently. In 1927 the archaeologist Toribio Mejia Xesspe performed the first scientific research on the lines.
It is still unknown why the Nazca culture created the drawings. Possibly it was a way to honor their gods, the American historian John Rowe said this theory. His disciple, the mathematician Max Uhle, ventured the hypothesis that it might be a giant calendar. It can also be a way to show their wits against the other cultures that were in the Palpa.
