The problem with the brain overwhelmed by theories or perceptions leads to thinks you vaguely discovered years ago and didn't put to writing. This seems to be one of them. However, I have also gone back into papers lying around in which I have found things I have vastly changed and corrected since, as well as things I discovered and then totally forgot.

[Moses]

As I mentioned in another tread.

The 72 days are only the translation of the the torah the five books of Moses.
The rest of OT translation lasted longer in to 180 or 120 BC.

Examination of language and stile show Jewish scholars first translated the Torah into Koine Greek in the third century BC[280]. Further books were translated over the next two centuries. It is not altogether clear which was translated when, or where; some may even have been translated twice, into different versions, and then revised.
The quality and style of the different translators also varied considerably from book to book, from the literal to paraphrasing to interpretative. According to one assessment "the Pentateuch is reasonably well translated, but the rest of the books, especially the poetical books, are often very poorly done and even contain sheer absurdities".

[Elijah]

You are correct, there are two translations of Genesis.
But mind you they are lies, however based on truths we can see were derived from the Hebrew Genesis.
One is Egyptian with Flood as 3090 BC.
And the other is Greek with Flood at 2958 BC.
Thus the Egyptian Greek Septuagint is actually two versions, only one of them original (280 BC July 21).

EGYPTIAN SEPTUAGINT
The Egyptian Genesis is based on 1290 BC Egyptian Papyrus produced by Ramses declaring the year 1800 from a 3090 BC Flood in which the calendar is framed as 340+1460, and also as Venus 600+1200. So it was created in year 340 or in 2750 BC instead of 2030 BC (which is Peleg's death), and then regarded as shifted 5 days by intruding Chaldean/Hitite Hyksos whom they claim did not build Memphis in 2030 BC but instead say Memphis was built in 2750 BC with calendar and that the kings invaded in 2321 BC when Peleg and Unas Sakkara died in year 768. (The true year 768 falls in 1602-1600 BC when Hamitic high priest Jannes declared Shemites an intrusion and attempted to evict them. He decided forced employment would work better, they get work out of them or they flee and migrate out. Israel took this personal as directed toward them alone since they regarded themselves as the savior for the Shemites, and many Shemites did accept them as such so that they grew to be 600,000 thru conversion and marriage.) So the shift of 5 days in the calendar was truly at the exodus (1513 BC) and instead was claimed to be an omitting of or inserting of 5 days at Peleg's death. This too has its alter-interpretation in that at Peleg's death of 2030 BC had switched from 360-day to 365-day calendar which is a difference of 5 days in every single calendar year, and not just omitting them in one year (debated as Peleg's death 2321 BC, or being later in the exodus). The 3090 BC Flood is based on claiming Thoth was always 1st month; that Phamenoth was never the 1st month. Thus it takes 720 years to move 180 leap days. To add 720 to Genesis requires belief that there never existed any difference between numeric ordinal (101 thru 200 years = 2nd century) and numeric cardinal (200 years) of counting centuries existed for the first six generations until Nahor. Thus 1st century 35 years and 1st century 34 years is translated as 135 and 134 years. This adds 600 years to help claim that Venus was not a half-cycle of 600 years in Adams year 2256 (600 years after the Flood year 1656),
but rather was a full 1200 year cycle after the Flood. Noah's year 1200 is thus regarded as 1200 after Flood instead of from his birth. The 120 additional years (720 =600+120) is not sloppily done as with Josephus who says Mahor was father at 120, and you have to guess whether this is Nahor. Rather the word for fallen Chaldea is Cainan as a people referred to as The Son of Arpaxad. There rise and fall occurred in 130 years whether it be building Ur (2369-2239 BC) after the global Flood in 2370 BC; or whether it be 177-year 1st dynasty fall at Peleg's death 2030-1900 BC when then the final 3rd dynasty fell; or be it final fall to Nimrod's death at 500 (thus 1900-1770 BC which is year 2256 AM). Thus Egyptian reckoning places Shelah as the son of 130-year Cainan, the sonm of Arpaxad. Shelah did die at 433 living 2333-1900 BC having died after Hitite destruction of 3rd dynasty Ur killing Ibbi-Sin. (Ibbi-Sin did not live to enthrone Ishbi-Erra on the throne of Isan, but rather it was at the 1st dynasty fall 2030 BC, that Ibbi-Sin rose up in 2029 BC as one of four kings of 2nd dynasty to enthrone Ishbi-Erra in 2017 BC. These kings are not listed because they are a collective, none of them taking sole rule until UrNammu did in 2009 BC.)
     The addition of this false 130-year Cainan results in 730 years and so 10 year must be reduced. This is easily done since the shift of 5 days in the 365-day calendar causes a 9-year shift in lunar dates. Since Nahor is the priest of Nannar (great mother) in Ur (for both Venus and moon) the reconstruction of Nahor and Terah's 159 years (29+130) can be altered to 149 years (79+70) by claiming that Nahor either marked or handled a 48-year Venus (x365 days) or 49 Julian year moon or 50-year moon (x365 days). Thus chronologies alter 2177 BC Nahor into the common 2167 BC and 2165 BC. Then Abram becomes debated as being 75 in Shulgi's 1st year 1991 BC or last year 1943 BC. (Eusebius says 1941 BC with a 774 BC Olympic Era.)

GREEK GENESIS
is very simple, it omits the 130 years knowing Cainan is not a person. Take 3090-3088 BC and subtract 130 and you get 2960-2958 BC. The span 2958-2956 is preferred because it marks 949 years or year 950 as Noah's Ptah (Mena), or the Ptah of Manu, or Ptah of Menes in 2009 BC. (Again Eusebius uses 2007 BC and a 774 BC Olympic Era so Abram is said to be born 2016 BC and 9 in 2007 BC with Nineveh founded in 2058 BC, all two years later.) However, both crhonologies are known for changing 159 years (29+130) to 149 years (79+70) and Japan chronology of a 3060 BC uses (179+70).

So yes alternative Septuagints of 280 BC exist, but from previous data that even the mesenger Gabriel (if he is human sent by God, whether a spirit angel or not) the numers of Daniel 1260 and 1290 and 1335 and 2300 are all numbers that false alternative chornologies for 6000 will end from the years 607 BC and 538 BC. Egyptian Flood year 3090 BC as 2256 AM ends in 654 AD. Japanese 3060 BC as 2256 AM ends in 684 AD (both are Moslem take overs); and because Josephus labels 3060 BC as a Flood in Adams year 2656 is the reason why Diocletians exaltation is in 284 AD as 400 years before Japan's 684 AD. Without 2.5 years of leap days, the Hindu Flood 3102 BC as 2256 will end 3744 years in 640 AD instead of 1975 AD (a difference of 1335 years) though its Flood 3102 BC is 1332 years before the true year 2256 in 1770 BC. Thus reality exists even if it turns out that everyone accredited as being an angel from heaven turns out to be 90% humans with the voice of God.
