>The funny thing is the ages seem to make 'sense' if you substitute years (365 days) for lunar months (29.5 days).
Or if you substitute 10 years for 1, taking the last digit, which always is 0, 2, 5 or 7 as an indication of the season, spring, summer, autumn or winter. Things become even "funnier" when one notices that with the numbers in the Septuagint not only the ages, but also the years of birth seem to make 'sense' after such a substitution.
Anyway, I also think that this is merely an interesting coincidence. This theory has been proposed by Robert Best in the book "Noah's Ark and the Ziusudra Epic: Sumerian Origins of the Flood Myth".
>I'm not saying there was a scribal error
No scribal error is possible in these numbers because the text states the years before birth, the years after birth and the sum of these two numbers. There were, however, intentional editions of the text. Not only in Genesis 5, but of the entire Bible, as evidenced by the texts in Qumran. Contradictions were removed, the meaning of unclear things was explained by small additions in the text, the grammar was revised, etc.
But does 'older version' always equate 'better version'?
Hint 1: The author of 1 Chronicles in chapters 1-9 didn't use the original version of the Pentateuch but a "newer" version.
Hint 2: Although the masoretic version of Pentateuch is surprisingly ancient (only the numbers in Genesis 5 seem to be edited), in the books of Samuel the situation is opposite: the masoretic version is very new. The version of Samuel in Septuagint was old, this old version, however, is not entirely preserved because in the Greek text we have now large parts have been replaced by the so called Kaige recension which is a new translation from the Masoretic text, most likely by Teodotion. It seems to me that if God wanted us to use the original version of Samuel (and Kings) then He would have preserved this original text, if not in Hebrew, then at least in Greek translation.

What is your problem?

According to the Masoretic numbers, Earth was created 4000 years before the rededication of the temple in Jerusalem by the Hasmoneans, 4000 years before the festival of Hanukkah was instituted in 167 BC. Coincidence?

Use the numbers in the Septuagint. ☺
