9 Historical Moments That Prove Aliens Have Visited Earth
5. The Nazca Lines
The Nazca Lines are a series of giant line drawings that are located in Perus Nazca Desert and believed to date back to as far as 500 BC. The drawings differ greatly in shape and size ranging from simplistic straight lines to more detailed depictions of animals, plants and humanoids. The lines are attributed to the people of the Nazca culture but both their purpose and their method of construction are unknown.
The large size of the Nazca Lines means that they just appear to be a series of random lines when viewed from ground level. This has led to a great deal speculation as to how and why an ancient civilisation incapable of flight would create intricate works of art that can only be viewed clearly from the sky. One explanation for the lines is that they served as an ancient landing site for extraterrestrials.
This theory states that the lines were actually created from the air by alien space ships. This theory also attempts to explain the purposes of the lines suggesting that the shapes and pictures served as aviation signals while the long, straight lines were landing strips.
