“In The Beginning”

Gen 1:1:  In the beginning God created the heaven and the earth.

There are seven words in the Hebrew texts:   בראשית ברא אלהים את השמים ואת הארץ׃    

Gen 9: 21 - Unto Shem also, the father of all the children of Eber, the brother of Japheth the elder, even to him were children born.

Moses 8:12 - And Noah was four hundred and fifty years old, and begat Japheth; and forty-two years afterward he begat Shem of her who was the mother of Japheth, and when he was five hundred years old he begat Ham... => making Ham the "firstborn" of the second wife.

"The children of Ham possessed the land from Syria and Amanus and the mountains of Libanus, seizing upon all that was on its sea-coasts; and as far as the ocean; and keeping it as their own. "

---Josephus, Antiquities of the Jews, chpt 6. v.2

"Canaan, the fourth son of Ham, inhabited the country now called Judea, and called it from his own name Canaan. The sons of Canaan were these; Sidonius, who also built a city of the same name; it is called by the Greeks Sidon.  But for the seven others, [Eueus,] Chetteus, Jebuseus, Amorreus, Gergeseus, Eudeus, Sineus, Samareus, we have nothing in the sacred Books but their names: for the Hebrews over-threw their cities..."

"Shem, the third son of Noah, had five Sons, who inhabited the land that began at Euphrates, and reached to the Indian Ocean. For Elam left behind him the Elamites, the ancestors of the Persians. Ashur lived at the city Nineve; and named his subjects Assyrians: ...Sala was the son of Arphaxad: and his son was Heber; from whom they originally called the Jews Hebrews. Heber begat Joctan, and Phaleg. He was called Phaleg because he was born at the dispersion of the nations to their several countries; [An. 2528] (26) for Phaleg among the Hebrews signifies division... These inhabited from Cophen, an Indian river, and in part of Aria adjoining to it."

"The son of Phaleg, whose father was Heber, was Ragau: whose son was Serug: to whom was born Nahor: his son was Terah: who was the father of Abraham: who accordingly was the tenth from Noah: (27) and was born in the two hundred and ninety second year after the deluge." => Noah was still alive/as was Japheth...   Terah died, [An. 1962] and was buried, when he had lived, to be two hundred and five years old: for the life of man was already, by degrees, diminished, and became shorter than before, till the birth of Moses after whom the term of human life was one hundred and twenty years.

Herodotus (~400 B.C. ) is the only one who equates Cheops with Kufu.  Siculus says Herodotus is wrong.

--- Theory ---

After flood, Egyptus claims the great pyramids and other ruins of Anunnaki (ancient ones) which puts her children centuries ahead of other descendants of Noah architecturally,  mathmatically, scientifically, musically, but they still have the problem that since Cain was cursed to be unable to GROW crops… that curse still followed them and the "egyptians" can not sustain themselves/their new city/empire agriculturally...

BUT, they still have the problem that since Cain was cursed to be unable to GROW crops… that curse still followed them and the "egyptians" can not sustain themselves/their new city/empire agriculturally...  The "egyptians" therefore decide that this “new world” is an opportunity to change their fate/start over, and they invade the “land of Shum”, west of them, which was lush/tropical.  

However, after they wipe out the people of Shum, there is a global earthquake, and “the land is divided” in the days of Peleg.  the continents move away from africa, causing a climate change alonge north Africa… and the Land of Shum becomes what we now know as "the Sarah desert"

There is less/similar evidence for both (Atlantis - https://www.ancient.eu/atlantis/) and Noah's ark/Flood stories (https://en.wikipedia.org/wiki/List_of_flood_myths) - in the case of Atlantis... it remains a "myth" - in the case of the Flood, they attribute all the different versions from around the world, back to Babylon (https://youtu.be/s_fkpZSnz2I)

Gilgamesh claimed, from his reading of tablets engraved on Lapis lazuli and secreted in a “copper tablet box”  loosened with “the ring-bolt made of bronze” that  this city was built by the seven sages or patriarchs of the Cainite pre-diluviun society and was not the city of his possessions.  ( Gardner, John and John Maier, Gilgamesh, Alfred A. Knopf, Inc. New York, 1984 Tablet I, Lines 4-6, 22-25) - https://youtu.be/Rd7MrGy_tEg
