IP, in your mind, what message is the text found in the Bible trying to convey, and to whom did God want that message to be delivered?
re Gen 1-11.
This material concerns the nations. Genesis does not sustain attention on Abraham and his descendants until 12, but the same promise immediately shows up. But more to the point, Gen 1 was written to show to the neighboring nations around Israel who was actually Creator. God put Abraham and his descendants in the place that connects three contintents so that the foundational truth of Gen 1-11 would be spread to the world, and then later the people attending Pentecost would likewise spread the Gospel to "the known world."
In competition were:
Canaanite god of Molech: fertility cycles, child sacrifice. The annual cyle consisted of preserving the sperm of the most successful farmer by his sexual intercourse with a shrine virgin. The child was then burned and the ashes were made into a drink to keep the alpha-farmer of the next season alive. There were many sub-versions of this practice in the little area called Canaan, and that is what God wished to stamp out.
Gen 1 showed a God who keeps creation going by his power and word. He stopped whatever was there before which displeased him and created a world fit for mankind in which each species keeps producing because of his divine plan. This separateness from nature itself is at enmity with Canaanite religion, in which the force of nature itself was to be preserved by the rituals.
Egypt: a belief that divine Pharaohs had defeated a pre-existing massive lizard and formed the residue of him into earth; he brought his divine power with him from Orion. This is why the pyramids of Geza are laid out to match Orion's belt--slightly off of straight alignment. The Pharaoh defeated him with the sword he wears--see the constellation--and to insure a continual succession of pharaohs and a stable world, the shaft of one pyramid aims at a female constellation, and it is said that the Pharoahs semen travels there to impregnate her for the upcoming year.
To this, Gen 1 says similarly that God is the creator and victor over the 'formless and void' that was there, not a Pharoah. God's son would come one day and provide redemption; it was not a matter of physically producing many children for a sure supply of the seed of a Pharaoh to keep the world stable.
Persia: a belief that a huge beast in the sea was defeated by a divine king to make this world. In addition there are kings who claimed their victory over stormy waters, and/or the flood, and one 'proved' this with an aqueduct under the Euphrates.
Hindi: a belief that the force of Sat (order) overcame the force of Asat (chaos) at creation and formed this world.
To both of these, Gen 1 says that it was God who righted the world from the watery chaos that was 'formless and void.' The Lord puts things right by his mere word; He spoke and it came into being--or form.
God wished to end the Canaanite practice by force and by the truth of Gen 1. And also by the account of Isaac, in which the total opposite of Canaanite religion happens: a son is born, miraculously instead of ceremonially, apart from normal sexual practice. The barrenness of both Abraham and Sarah are exhibited as the counterpart of the alpha-farmer selecting a delicious virgin for sex; and then Isaac is 'resurrected' from apparent death in the stalled sacrifice. In his place, is the sacrifice of an animal as a reminder of the redemptive promised Seed of Gen 3. That practice forms the basis of Judaism, in place of the death and primitivity of child-sacrifice.
As for the regional impact of early Genesis on its neighbors, I visited the national museum of Moldova a few years ago (3 countries away from Israel) and there was an ancient fragment kept there about the miraculous birth of Isaac that dated from the 2nd millenia BC when Judaism originated. Word gets around. People may confuse the physical descendancy with the redemption people who would be formed by the coming Seed, but at least the supernatural side of Isaac's existence was understood and was intact that far away from Israel and during that time period.
