It appears that the Aryans were actually Adamites (who were Caucasian in appearance). These Aryans lived in Western China (Tarim Basin). You see Adam and Eve were driven from the Garden to the east--the Tarim Basin or Xinjiang. They built magnificent cities and overall were a sophisticated people. It was these Aryans that gifted a higher level of civilization to the Chinese. It was also these Aryans (Whites) who established a proto-Hinduism in Northern India (the Rama Empire). (Cain may have a bit later added his own twist to Hinduism with the Hindu trinity: Brahma, Vishnu, and Shiva.)
According to this very plausible theory Noah's flood would have occurred around 3800 BC. (Couldn't it have occurred earlier?--say around 5500 BC?) You see, I'm trying to reconcile the flood that created the Black Sea further west with this flood that took place in the Tarim Basin.
Now before this regional flood in the Tarim Basin (Noah's flood) it had to be these White Adamites/Aryans who are the players in the great Aryan epics, such as the Mahabharata. It may very well be that that story is about a family feud--between the House of Seth and the House of Cain--or a conflict between two families within the Sethite line. Thus the Bhagavad Gita is a spiritual treatise that was the work of the Aryans. It is my opinion that the happenings in Genesis 6 are elaborated upon in the Mahabharata. (In the pre-flood world of the Mahabharata high technology was in use: space/aircraft that resemble the UFOs (flying saucers) and speculative fiction spaceships found in comics and movies.) This means that this epic is older than 3800 BC. 5500 BC perhaps? If this date for the Mahabharata war is accurate--and if we are to believe that Nibiru/Planet X/Nemesis is true--then said war occurred sometime after said planet (actually Nibiru is the sun's partner star that has its own planet(s)) came into our solar system. Hmmm.
What I'm wondering about is this thing about Rama having been an avatar of Vishnu--and Krishna later being an avatar of Vishnu also. Could it be that Satan was trying to counterfeit the three manifestations of God?: the Father, the Son (being the image of the Father), and the Holy Spirit (the infinite mind of God--omnipresent and omniscient). Satan, through Cain, coming up with the Hindu trinity of Brahma, Vishnu, and Shiva?
If you consider the name "Abraham," you can see how it is reminscent of Abraham's lineage going back to Northern India and the Tarim Basin. "Abraham" is similar to "Brahma." The Aryans were the Brahmin--scholars bringing enlightenment--to India.
Then it can be said that the Aryans, after Noah's flood, went westward and took over the already present Sumerian civilization (becoming known as the Akkadians). These Aryans, descended from Noah's family, were starting over again as far as civilization was concerned. It may very well be that by Noah's time (before the flood) the Sethites had declined in terms of their technology. They no longer possessed advanced aircraft; they were getting around in horse-drawn chariots and wagons. Most likely the coming of Nibiru (about 3100 BC) caused such destruction that civilization collapsed (once more).
Earlier the Kenites (Sons of Cain) also came along from Nod (to the east) to influence the Sumerians. We are told of seven sages (Abgal) coming into Sumer from the east. These Abgal were created by Enki (anagram for Cain). Oannes was the leader of the Abgal. He was supposed to have been a fish god--Dagon being another name for him. "Oannes" is another way of saying Enoch (son of Cain). The fish meme may be symbolic of how the Kenites (Cain and his son Enoch) were not overtaken by the flood. Manu, the Vedic corruption of Noah, was aided by a fish when a flood came upon Northern India. This could be speaking of Naamah--daughter of Lamech (a son of Cain)-- who may very well have been Ham's wife. (Ham appears to have had a tendency to perversion. Not only did he marry a Kenite woman, but he uncovered his father's nakedness--had sex with his father's wife--the offspring of said union was Canaan.) Therefore part of the Kenite line went through the flood by way of Naamah marrying Ham.
Thus the Aryans brought enlightenment to Mesopotamia and Egypt. They may have been adding on to earlier contributions by the Atlanteans. The Aryans (children of Shem, Ham, and Japheth) would raise the level of civilization to its highest levels--bringing about its greatest achievements. These Aryans being the descendants of the last of the Anunnaki: Adam and Eve.
Plato pointed out that civilization is cyclical: it rises and it falls and it rises again. It could be that the flood of 5500 BC that devastated the area of the Black Sea (and by extension Sumeria)--turning that lake into a sea that is connected to the Mediterranean--left the region in a pitiable state as far as culture and the other trappings of civilization are concerned. And about 3150 BC a bolide (comet or asteroid) struck the Mediterranean, leaving much devastation (similar to the comet that exploded over Ireland in 562 AD, which severely affected much of the Europe's weather for at least a decade). Then the Aryans (descendants of Noah) came along and raised it back up again--and even to a higher state of accomplishment. It may be that the peoples in the Mediterranean and the Middle East at this time were the children of Adamites who had migrated from the Tarim Basin before the flood of Noah.
