While this incident made alterations to a lifeless moon, the first beings to notice the insignificant blue world the moon orbited were the enigmatic, seemingly omnipotent Celestials. It was the Celestials who were the first alien beings to step foot on this strange world known as Earth.
Paleolithic humans were gathered by the Celestials, who created two new races from the early proto-humans: the godlike Eternals, and the grotesque Deviants. The early humans, the control of their experiment, were advanced in their evolution and were also given genetic potential to someday develop super abilities.
