This has been suggested. Let's think about it.
There are about 13 "moons" in a year, so you would divide the age ("years")
given for each patriarch by 13. Methuselah would have a lifespan of 969/13
= about 74 years, Lamech lived 777/13 = about 60, etc. This sounds
reasonably plausible to us, given our present lifespans.
But if you apply this consistently in Genesis 5 & 11, what happens? Enoch
would be born when Jared was 162/13 = 12, ...and Enoch would have
Methuselah when he was only 65/13 = 5!
I don't think so.
