Michael,
Or, the fragments of the more ancient Adamic story, pieced together for Genesis from Mesopotamian lore, are about an incarnate Adam and Eve, two full grown, educated adults, Son and Daughter of God, from another world in Gods creation, who spoke a language understood by the resident but fallen "crafty beast" on a previously populated, evolved earth.
In my understanding all evolved worlds in the Lords creation receive an Adam and an Eve in succession form the 1st spiritual leader, The Planetary Prince. Ordinarily they are to pick up where the last administration left off as the visible representative of the universe government under the Son of God. But a tragedy occurred, "there was war in heaven", an ideological war. Our "prince of this world" fell into rebellion against the rule of the Father, through the Son and on the earth.
Being fully versed and duly warned about the difficulty of the task at hand, Adam and Eve arrived on the fallen, divided earth in the Garden previously prepared for them by the inhabitants who had remained loyal to the rule of the Father. They spent the first 6 days surveying the garden and familiarizing themselves with the people and the Garden. On the 7th day they rested.
In due time a second default occurred, while not a deliberate, open rebellion such as Lucifer's manifesto, Eve succumb to impatience over the backward and deplorable state of affaires left on the earth in the wake of the Princes fall. Outflanked by the suggestions and trickery of the brilliant "fallen prince", Eve decided that injecting her own plan, her own superior genes into the gene pool, would greatly facilitate the degenerate state of affairs on earth. The deed was done, the result was her second Son Cain who's real father was a Nodite from outside the garden.
Realizing what had occurred and being unable to contemplate being without his life partner, Adam deliberately did the same in order to share Eves fate; loss of immortality status. They became like one of us wherein death is mans normal path.
The administrative affairs of the planet were then put under the receivership of the emergency Sons, The Mechizedeks. It was decided by the creator Son Michael that our fallen world among millions under his creational jurisdiction would be the world of his required incarnation. Jesus aka Christ Michael is now the titular "planetary prince" of our world.
Fairly simple stuff and much more consistent with the fragments we have in Genesis.
