Genesis chapter 6 Star Chart: Clockwise from when "the (Argo) sons of God ("the angels that sinned" -- 2 Pet. 2:4-5 or "the angels which kept not their first estate, but left their own habitation" -- Jude 6) saw the (Gemini) daughters of men that they were (solar and lunar buttocks) fair; and they took them (Gemini) wives of all which they chose" in 2424 B.C. (6:2) till "the same became mighty (Gemini) men which were of old, (Hercules and Ophiuchus) men of renown" in 2304 B.C. (6:4) is 120° years since "his days shall be an hundred and twenty years" (6:3). See the noncanonical books of Jasher, Jubilees and Enoch for more details on what went on here. Remember that Paul refers to “Jannes and Jambres” (2 Tim. 3:8) quoting from Jasher 79:27; and Jude says "Behold, the Lord shall arrive with millions of the holy ones in order to execute judgment upon all" (Jude 14-15) quoting from 1 Enoch 1:9; and Jubilees is found in the Dead Sea Scrolls.
From when Noah was commanded to "Make thee an ark (Argo) of gopher wood; (red radius) rooms shalt thou make in the ark, and shalt (red radius) pitch it within and without with (red radius) pitch" in 2424 B.C. (6:14) till "I do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall (black Zodiac) die" in 2304 B.C. (6:17) is 120° years since "his days shall be an hundred and twenty years" (6:3).
Noah Was a Just Man and Purebred in His Ancestry, and Noah Walked With God
6:1 And it came to pass, when (Gemini) men began to multiply on the face of the earth, and (Gemini) daughters were born unto them,
2 That the (Gemini) sons of God saw the (Gemini) daughters of men that they were (solar and lunar buttocks) fair; and they took them (Gemini) wives of all which they chose.
Giants were the result when this happened. 2 Peter 2:4, “for if God spared not angels when they sinned, but cast them down to Hell”; Jd 1:6, “angels which kept not their own principality, but left their proper habitation”; and in the Book of Enoch.
3 And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
4 There were (Gemini) giants in the earth in those days; and also after that, when the sons of God came in unto the (Gemini) daughters of men, and they bare (Gemini) children to them, the same became mighty (Gemini) men which were of old, (Gemini) men of renown.
"and also after that" -- These words are introduced in order to shew that the Nephilim existed not only in primitive ages, but also at the time of the Exodus from Egypt, as would be implied by Numbers 13:33 and “Nimrod,” Genesis 10:8, and “Og,” Deuteronomy 3:11. The continuance of the Nephilim in later times may be due to fallen angels taking wives after the flood as well as before. That is what is meant by "and also after that."
Such were the Titans that made war against Saturn, begotten by Ouranus, who were not only of bulky bodies, but of invincible strength, as Apollodorus (p) relates, and Berosus (q) speaks of a city about Lebanon, called Enos, which was a city of giants, who were men of vast bodies, and of great strength, inventors of arms and music, were cannibals, and exceedingly debauched.

5 And God (Argo) saw that the wickedness of man (Hercules) was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
6 And it repented the Lord that he had made man on the earth, and it grieved him at his heart.
7 And the Lord said, I will destroy man (Hercules) whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
8 But Noah found grace in the eyes of the Lord.
9 These are the generations of Noah: Noah was a just man and perfect in his generations (purebred in his ancestry), and Noah walked with God.
10 And Noah begat three sons, Shem, Ham, and Japheth.
11 The earth also was corrupt before God, and the earth was filled with violence.
12 And God (Argo) looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted (hybridized) his way upon the earth.
13 And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
14 Make thee an ark (Argo) of gopher (Cypress) wood; (red radius) rooms shalt thou make in the ark, and shalt (red radius) pitch (kopher) it within and without with pitch.
15 And this is the fashion which thou shalt make it of: The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.
The dimensions of the ark, as here given, are somewhat smaller than in the Assyrian account. Assuming that a cubit measured 1½ feet, the ark was 450 ft. long, 75 ft. broad, and 45 ft. high. It will be noticed that the breadth is exactly one-sixth, and the height exactly one-tenth, of the length. In the Assyrian account we miss these proportions. The length is not given, but the height and breadth are the same, viz. 120 cubits, or 180 ft., broad and high. Berossus, the Greek writer of Babylonian traditions, records that the ship of the Flood was 5 stadia (about ? of a mile) long, and 2 stadia (about ¼ mile) broad.
But if the Jewish and Egyptian cubit, the cubit of the Scriptures, as Dr. Cumberland (r) has shown it to be, consisted of twenty one inches and upwards, the ark according to them must be very near twice as great, and so more convenient for all the ends to which it was designed; for, as he observes, the cube of such a cubit is very near double to the cube of eighteen inches, and therefore so must the capacity be.(r) Of Scripture Weights and Measures, ch. 2. p. 56, 57.
16 A (solar) window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it.
The ark itself, which was finished with a roof raised up a cubit high in the middle
17 And, behold, I, even I, do bring a (red radius) flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die.
18 But with thee will I establish my covenant; and thou shalt come into the ark (Argo), thou, and thy (Gemini) sons, and thy wife, and thy sons' (Gemini) wives with thee.
19 And of every living thing of all flesh, two (solar halves) of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.
20 Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive.
21 And take thou unto thee of all food that is eaten, and thou shalt gather it to thee; and it shall be for food for thee, and for them.
22 Thus did Noah; according to all that God commanded him, so did he.
