The White Race (Adamic Race) was born out of the Mesopotamian Basin around 7560 years ago.
The Watchers, the angels that landed at Mt. Hermon, they took for themselves wives from among the beautiful daughters of Adam.
The Flood was localized to the Mesopotamian Basin and was sent by God Yahweh to punish the White Adamites for racemixing with the Angels. The Flood killed many Whites, Nephilim, and their bastard Nephilim children.

Noah was saved out of the Flood by Yahweh because Noah was perfect in his race, he had not mixed, see Genesis chp6, ditto for all of Noah's children.
The Ark landed upon the Caucasian Mountains at Mt Ararat. Out of the Ark came eight souls, Noah and his wife, and his three sons and their wives. The three sons, Shem, Japeth, and Ham each spread out across the land and had many children.

Several branches of the White race went far to the East, establishing the civilizations of China and Japan. Inevitably these branches racemixed, producing the bastard bestial people we see today in those places. Japan being isolated kept more of its European DNA and phenotypes, whereas with China, so many invasions and wars have basically wiped away the vast majority remnant White DNA. See the Uighurs in China for an example of another Asiatic group with a large percentage of White DNA.

Edomite-Jews in academia don't want Whites to know about the true racial past of Whites vs the Nephilim (fallen ones) and have strongly repressed it. The Beast races don't want to acknowledge that Whites created their civilizations, so they deny DNA tests on ancient corpses to keep up the pretense. This why the most ancient of American-Indian corpses are never DNA tested, because we would find White DNA.
It's the same reason for why the 1st Emperor of China, the Yellow Emperor, will never be shown to the public or DNA tested.

Same story for the Whites Gods of Central and North America. See Vrirococha.
Whites create civilization.
Whites are the only children of God.
