Noah and The flood

Gen.7

[1] And the LORD Enlil said unto Noah, Come thou you and all thy your house into the ark; for thee you have I seen righteous before me in this generation bloodline.
[2] Of every clean beast thou you shalt take to thee you by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.
[3] Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.
[4] For yet seven days, and I will cause it to rain upon the earth forty 40 days and forty 40 nights; and every living substance that I have made will I destroy from off the face of the earth.
[5] And Noah did according unto all that the the LORD Enlil commanded him.
[6] And Noah was six hundred 600 years old when the flood of waters was upon the earth.
[7] And Noah went in, and his sons, and his wife, and his sons’ wives with him, into the ark, because of the waters of the flood.
[8] Of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth,
[9] There went in two and two unto Noah into the ark, the male and the female, as GOD Anu had commanded Noah.
[10] And it came to pass after seven days, that the waters of the flood were upon the earth.
[11] In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month (77 days?), the same day were all the fountains of the great deep broken up, and the the windows of heaven portals were opened.
[12] And the rain was upon the earth forty days and forty nights.
[13] In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, into the ark;
[14] They, and every original beast after his kind, and all the pure/original cattle after their kind, and every creeping thing that creepeth upon the earth after his kind, and every fowl after his kind, every bird of every sort.
[15] And they went in unto Noah into the ark, two and two of all flesh, wherein is the breath of life.
[16] And they that went in, went in male and female of all pure flesh, as God had commanded him: and the LORD shut him in.
[17] And the flood was forty 40 days upon the earth; and the waters increased, and bare up the ark, and it was lift up above the earth.
[18] And the waters prevailed, and were increased greatly upon the earth; and the ark went upon the face of the waters.
[19] And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered.
[20] Fifteen cubits 6.75 meters upward did the waters prevail; and the mountains were covered. (Then it’s likely that the ark was built on a mountain top)
[21] And all flesh died that moved upon the earth, both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth upon the earth, and every man:
[22] All in whose nostrils was the breath of life, of all that was in the dry land, died.
[23] And every living substance was destroyed which was upon the face of the ground, both man altered humans, and cattle, and the creeping things, and the fowl of the heaven; and they were destroyed from the earth: and Noah only remained alive, and they that were with him in the ark.
[24] And the waters prevailed upon the earth 150 an hundred and fifty days.
