Ancient Sumerian culture is fascinating for many reasons, not the least of which is their belief in ancient astronauts or gods from the sky. There are ancient texts that describe flying machines and advanced technologies that are far beyond anything that was known at the time. There are also depictions of beings with unusual features, such as large eyes or extra limbs. This evidence suggests that the ancient Sumerians were visited by beings from another world, and that they played a role in the development of Sumerian civilization. Whether or not you believe in ancient astronauts, it's clear that the ancient Sumerians had a unique perspective on the cosmos.
