The greatest mysteries are sometimes hidden under our gaze and we do not notice it. It took until 1927, when a Peruvian pilot who was flying over the region noticed it, for the world to rediscover the mysterious Nazca lines, from the name of the desert plateau where these lines are found in the land that extend for variable lengths (the longest measures 23 kilometers), made of a strange white substance that, analyzed by Dresda University, turned out to be a kind of crystalline glass powder.

For official archeology it is geoglyphs traced by a civilization flourished in the region between 300 B.C. and 500 A.D., probably for reasons related to a cult, perhaps as a trace to follow during the ritual journey of ancient religious ceremonies.

Are Nazca lines astronomical calendars?

Alternative interpretations speak of a use as irrigation channels, given the extreme aridity of the region, or as astronomical calendars, since some of the more than 800 figures would seem to refer to constellations.

The giant spider, for example, would be the representation of the Orion constellation, while the three straight lines passing over the drawing would be aligned with the three stars of the Orion belt; the monkey, discovered in 1954 by Maria Reiche, instead it should represent the Big Dipper

Nazca lilnes are not all the same and they would have been drawn at least in two different moments, first those representing animals or human figures, then geometric drawings (more numerous).

Precisely geometric designs to our eyes appear, if viewed from above, like real landing strips, but who could land two thousand years ago in a region still difficult to access in Peru?

Who and how did the Nazca lines track?

Among the many theories arising in this regard, it was also thought of the Atlanteans before the disappearance of their city state, but the followers of the theory of ancient astronauts think otherwise and point out that one of the most mysterious figures seems to represent an astronaut (even if the official archaeologists identify him as a fisherman), with a helmet on his head, while another figure represents a star.

Legends have flourished in Nazca and other areas of Peru relating to inhabitants of the sky, or “gods”, who descended to Earth, legends that could have a fund of truth.

If an ancient extraterrestrial expedition had arrived on earth two thousand or more years ago would have found on the plateau of Nazca one of the best landing places to be able then to take samples of the soil, since the area is rich in minerals, from iron to gold to uranium.

The hypothesis of ancient astronauts

Mineral samples could have been collected and analyzed by automatic probes similar to the many US rovers, from Vikings to Pathfinder, from Spirit to Opportunity and Curiosity, which landed on Mars leaving behind visible traces.

These traces, once the probes (or real UFOs with alien crew) were gone, would then set up the guidelines from which the Nazca civilization elaborated its geoglyphs, to remember or perhaps to recall the gods who in ancient times descended from heaven.

The “gods” were no longer going back down to Nazca, but the lines remained, preserved by the dry and slightly windy climate of the region, until modern man with his heavy means of transport and his activities (like the construction of the Carretera Panamericana Sur) started to erase them, as happened to the figure of the alligator.

Further clues could be found by widening the analysis to the subsoil, but the Peruvian government, which did not object when it came to building the Carretera and putting the lines at risk, has decided not to give its consent to further archaeological excavations considering the area sacred and preferring to concentrate the research at the Cahuachi ceremonial site.

It would almost seem that you do not want to find out what is hidden under the mysterious Nazca lines: is it possible to demonstrate that there is really evidence of an ancient landing of alien probes or UFOs, but is there no interest in making it known to the world? To think badly, it's a pity, but sometimes you got it, they say.
