The Nazca Lines Theories emerged because, according to dating, the 13 000 lines and 800 geogíficos range from 550 to 650 years A.C and the controversy over to identity of those who created the tracks and to know the real purpose of these enigmatic draws, that nowadays continue more relevant than ever.
At first any archaeologist could explain the reason its existence, which led to different theories: one of these is the extraterrestrial theory suggested by an amateur archaeologist from Switzerland named Erich von Däniken, according to which the drawing was a track trapezoidal landing craft built by aliens who visited the Earth long time ago and the Giant portrayed in the hillside (“the Astronaut”) is the figure of the alien testified by the Nazca.
Far from being a great story, but perhaps the lines were not exactly landing strips, as suggested Däniken, this theory coincides with other somewhat similar traces of the “gods of old” left as testimony to that contact. After all … lines can only be appreciated from the air.
The theory most widely accepted by scientists is the theory of the calendar. According to Maria Reiche, the drawings are the schedule and map of the sky world’s largest, the countless lines that cross the desert in all directions were used to observe the movements of the Sun and the Moon. Using this method the Nazca Indians could announce the change of seasons and use this knowledge for agriculture. Some animals drawn indicate the direction in which a large seasonal constellation can be seen. But some people disagree with this theory, a strong wind blowing Palaca called seasonal round in this region, it is often very foggy, but during the day is sunny in the morning and evening are usually covered, before sunrise or after sunset is too dark to see the drawings, in other words the Nazca desert is not ideal for making meteorological observations.
Another of the many theories says that the answer lies in the Nazca pottery, which is one of the masterpieces of ancient Andean civilization. It is characterized by bright colors, all the gods designed Nazca pottery in their mouths are agricultural products, this shows the importance he gave this village to agriculture. All drawings of animals in the desert are repeated in ceramics. The only difference is that the drawings in the desert are made with a single unbroken line, another feature is that there is always a segment of the drawing that is open, and the drawings are made in one stroke without interruption.
Land of Nazca is arid with no rain all year. From generation to generation have been survived working the little land on the banks of the river, planting appropriate to the sandy soil grains. The land is poor and dry, thanks to the wells were able to continue farming.
The meaning of the Nazca drawings and the need for water would be another possibility. The mirage of water in the desert can be seen when the winds subside. The drawings of the desert are covered by this water phantom. This is precisely what the Nazca Indians must have seen. The multitude of lines in the desert were then ditches to channel water phantom, the drawings were made by a single line without breaks that could serve as receptacles for water. This is not all about the appearance of the mirage in December coincided with the arrival of “El Niño” phenomenon, every seven years. The dry climate that produces the Humboldt Current off the coast of Peru changes abruptly with the arrival of El Niño, moist air enters the coast bringing heavy rains in the interior. Although El Niño causes extensive damage to the world to Nazca Indians was an emissary who brought rain to the region, including 1,500 years ago the existence of El Niño was known. Was this what the Nazca expected, the life-giving water.
At the end none of these theories are certain for sure, the true is that the lines extend hundreds of kilometers and its geoglyphs are only see fully from the air; probably came from there those “gods” of old and perhaps where they are possibly the answers to the mystery
