No matter if you are a conspiracy theorist, a scientist or an ET specialist, we can all agree that Nazca Lines in Peru are most certainly an unexplained natural phenomenon that were only discovered when air travel become popular as they only make sense when seen from above.
The lines which are in fact geoglyphs are etched into the earth surface. The drawings cover an area of 450 km² and consist of 800 straight lines, 300 geometric figures and 70 different animal and plant designs, the largest of which is 200 metres wide. Over the decades scientists have speculated theories of aliens, UFO landing strips, offerings to the gods, stellar constellations but to date the only thing they know is that they date back 1500 years and no one can explain how these geoglyphs came to be.
