Complete History of the Sumerians | Sun People: Earth's Oldest Civilization | African-Indo-Euro-Asia

The Sumerians are the most ancient civilization on earth that flourished in Mesopotamia (modern-day Iraq) around 3500 to 1900 BCE. They are credited with inventing writing (cuneiform script) which predates all ancient texts, developing advanced irrigation and city techniques, and creating one of the earliest known urban societies.

Zecharia Sitchin was a controversial author who proposed alternative theories about the Sumerians and their interactions with extraterrestrial beings. He claimed that Sumerian texts, particularly their mythologies and writings, contain evidence of ancient astronauts visiting Earth from a planet called Nibiru. Sitchin's interpretations suggest that these visitors genetically engineered humans to serve as a labor force.

While Sitchin's ideas gained a following among some enthusiasts and alternative historians, they have been widely criticized by mainstream scholars.
