For the past 30 years I've been attempting to understand the cultural context of Genesis so that I can understand what the material meant to the people who are named there. Without this information we are likely to misinterpret and misrepresent the Word that they received. This means identifying the point of origins of Abraham's ancestors.
Using the genealogical data, I've idenitified Abraham's ancestors as originating in Africa. Genesis 10:6 tells us that they were Kushites, that is, descendants of Ham and Shem, whose lines intermarried. The pattern of intermarriage among these two ruling lines is identical to the pattern found among Abraham and his Horite kin. As teh Horites were a caste of ruler-priests associated with the Nilotic peoples, it is safe to safe that Abraham's ancestors can be traced back to the Nile Valley.
However, The king lists of Genesis 4 and 5 suggest that earlier ancestors came from the region of Northern Nigeria and Lake Chad. Nok (Enoch), Kano (Kain) and Bor-No (Noah's Land) are in Nigeria, and Nubia and Kush were Nilotic civilizations that included Egypt, Sudan and Ethiopia. There is also the genetic marker of the Nubians of the Nile which indicates that they migrated from further south in Africa. This supported a long-standing suspicion on mine and stirred me to investigate cosmologies that might link rulers of west central, eastern and sub-equatorial Africa.
What are the most fundamental elements of their cosmology? The evidence suggest 2 things: crosses and blood . Let us look are 3 specimens that would support this view.
iron ore ochre plague from the Blombos Cave (southern Africa) carved with geometric patterns.  This is the oldest known symbolic artifact and around the rim of the plaque are crosses. The red ochre came from mines that were in operation between 80,000 to 100,000 years ago in the Lebombo Mountains. We are not speaking here of small hallows in the earth, but of major mining operations.
“One of the largest sites evidenced the removal of a million kilos of ore. At another site half a million stone-digging tools were found, all showing considerable wear. All of the sites in fact produced thousands of tools and involved the removal of large quantities of ore; and while some were open quarries, others had true mining tunnels.” (From here.)
What was the significance of this red ore that was ground to powder and used to paint ritual objects and to bury dead rulers? It is generally agreed that the red ochre was a symbol of blood, the liquid of life. Stan Gooch explains:
Everyone, both heretic and orthodox, and including the present-day users of ochre themselves, agree that it represents blood. A very common interpretation, and one that we can readily accept here, is that just as a new baby comes into the world covered with blood, so the corpse must also be covered with blood to facilitate, or perhaps cause, the re-birth of the deceased in the spirit world beyond. Birth blood is therefore one very probable meaning.
A further significance (borne out also by much other evidence) is given by the Unthippa aboriginal women. They say that their own female ancestors once caused large quantities of blood to flow from their vulvas, which then formed the deposits of red ochre found throughout the world. So we can say that red ochre also represents menstrual blood: in both cases therefore female blood connected with the birth process. (We shall later be able to be even more precise and say that ochre is the menstrual blood of the Moon Mother; or more properly, the placental blood which covered the Earth when She gave birth to it.)"
The priesthood emerges out of this primeval perception of blood as the substance of life and a substance which can both pollute and purify. The Hebrew root "thr" = to be pure, corresponds to the Hausa/Hahm "toro" = clean, and to the Tamil "tiru" = holy. All are related to the proto-Dravidian "tor" = blood. (The Dravidians mined gold in Africa and were merchants along the length of the Nile.) These are cognate languages in the Afro-Asiatic language group and it is from these peoples that we receive the institution of the priesthood and an understanding of blood as both polluting and purifying.
It appears that the cosmological concern with crosses and blood was carried into the Nile region by people migrating from southern Africa. DNA analysis in ancient Nubians supports the existence of gene flow between sub-Sahara and the Nile valley. 
Specimen 2: The Phoenician Alphabet. Note that the Tau is a cross within a sphere. The Tau often serves as a symbol of the Cross in Christianity.
He wrote: "And so people are all but ignorant of the fact that time really is the wanderings of these bodies, bewilderingly numerous as they are and astonishingly variegated. It is none the less possible, however, to discern that the perfect number of time brings to completion the perfect year at that moment when the relative speeds of all eight periods have been completed together and, measured by the circle of the Same that moves uniformly, have achieved their consummation."
The cycle takes between 25,000-28,000 years to complete and is called a "Great Year." According to Giorgio de Santillana and Hertha von Dechend there are over 200 myths from ancient cultures that refer to a Great Year.
The word is total:
it cuts, excoriates
cures or directly kills
amplifies or reduces.
According to intention
it excites or calms souls.
The phrase "In the beginning was God" is not found in Babylonian prose such as the Gilgamesh Epic, but it is found in Africa. The following is a song of the BaMbuti Pygmies:
In the beginning was God
Today is God,
Tomorrow will be God.
Who can make an image of God?
He has no body.
He is as a word which comes out from your mouth,
That word! It is no more,
It is past and still it lives!
So is God.

There has been no immigration into the lower Nubia area from Asia according to Lycotte's Y chromosome study. The singular Nubian haplotype would be the expected result of the unique marriage pattern revealed by the Genesis genealogical data.
