Who were the Sumerians—and where did their extraordinary knowledge come from? Explore the mysteries surrounding the world's first known civilization in this full episode of Ancient Aliens.

From the invention of writing, mathematics, and the wheel to the mysterious cuneiform tablets describing the Anunnaki, this episode examines one of history's greatest archaeological puzzles. Investigate the Epic of Gilgamesh, the Great Flood, the legendary city of Ur, Göbekli Tepe, Baalbek, and the ancient texts that some believe preserve humanity's earliest encounters with visitors from the stars.

Did the Sumerians lay the foundation for civilization on their own, or were they guided by beings who descended from the heavens? Discover the discoveries, ancient artifacts, and controversial theories that continue to reshape our understanding of humanity's earliest history.
