HERE IS THE SUMERIAN KINGS LIST: The king who ruled the longest was Enmenly-Anna who was the King for 43200 years. Of course they were not Humans. They were Humanoids, and Anunnaki. They ate the "White Powder Gold", to stay alive that long. "Google" "White Powder Gold" and you will see what it can do - - and it is available today. I only know of one source I can say works, because of Personal Experience.
