Nazca Valley
The strange lines and geoglyphs of Nazca Valley, representing the mystical images of animals (spider, condor, hummingbird), and even human (astronaut) are the mysterious enigma of Peru. Only with the beginning of the space era our contemporaries could see these images. Because from the earth we only can see the multiple riffles in the soil of the sand and the rubble. Who, how and why did leave us this message? It is unknown. Perhaps the humanity will need much time to solve this amazing puzzle.
