Who is Satan?
The Ancient Sumerian's worshipped the creator of Humanity as Enki who they stated created the race of Adamu [meaning humanity] and into their blood Enki put the secrets of the blood of the Gods. And in doing such Enki created the new race with a special spiritual purpose, to ascend and become shining ones [God means shining one in the ancient language]. The Creator God, Enki was also called Satana by the ancient Sumerian's.
The name of the ancient religion was SATya, which is Sata ya. Which is named after Sata...na. And holds the same meaning: Eternal Truth.
