Could it be that humans were intended for a purpose that required only manual labor and thus were to be kept "dumbed down"?
Zech Sitchin writes about this theory. He refined Van Danieken's Ancient Astronauts kickoff. He postulates rounds of genetic experiments where man is either dumb as a rock (and doesn't make a good slave) or too smart to make to good slaves.
How do you know that these two beings are not the same?
Maybe they were on the same crew, a la Captain Kirk of the Enterprise fame. They were supposed to be supervisors and Big J was crew chief; Satan didn't like this. So they disagreed.
Maybe all this was pre "Prime Directive" times: "New Management" called a halt to the colonization, doing the "God act" scheme.
Or Civil War at Home Base cut the supply lines and the colonies were abandoned.
It could be that the different sequences (Babylonian Gigamesh days; ancient Hebrew Israel, OT days; Jesus, NT days and even the Islamic overture) were all different aspects of various members of the "crew" taking over in orderly or not so orderly "change of commands".
This goes along with the "Elohim" being a plural grouping of such "god-like" cadets or space soldiers. (Space cadets?)
A greater and lesser hierarchy of Gods would be seen here; and history might well support that better than the singular god supposition.
