Ancient Sumerian writings reveal the earth was ruled by eight immortal kings for 241,200 years. According to the Sumerian mysterious text our earth was ruled for many thousand years by many immortals kings. The time frame of earth is not as we know today and it is much more beyond our imagination and knowledge.
More than a dozen copies of a mysterious text referred to as the Sumerian King Lists have been uncovered over the years by archaeologists in regions as disparate as ancient Babylon, Susa, and Assyria. They are all believed to be copies of a single original manuscript which is thought to have been written during the Third Dynasty of Ur by most historians, although some believe it might have been written even earlier. The best-preserved example of this ancient text is called the Weld-Blundell Prism
and is on public display in the Ashmolean Museum.
