Frankly, I think much of the material in the pre-history biblical material (Genesis 1-11) is problematic.....
Frankly, I am at a bit of a loss to know why it matters if the lifetimes in the Mesoretic or LXX texts are correct in a mathematical sense. How does it impact Law and Gospel if someone lived 150 years or 100 years?
No one knows what Hebrew texts the LXX used in order to translate into Greek. All we have is THEIR translation. And yes, generally we know the meaning of the GREEK words they used, but we have no clue what the Hebrew words were... and may be more or less aware now as to what those Hebrew words meant in say 1400 BC.
Interesting (to me) to see how SOME Protestants go on and on about how infallible, how smart, how authoritative some Church Fathers are.... the very same ones they claim are WRONG about the Eucharist, about Baptism, about Mary, about pretty much everything.
Meanwhile, we have massive numbers of Christians essentially denying that Jesus is the Savior, insisting that each person is the infallible/unaccountable interpreter of Scripture, etc. - and none of this seems to concern them a bit. All kinds of weird new dogmas are being invented out of thin air - and the church divided by them - and they don't give a rip (because they likely are doing that) But did some dude no one has heard of .... does he have a child when he was 135 years old or 35 years old? THAT is THE most important issue in all Christianity, THE issue they think is the great danger, the big deal. And I think of some verse about being divided by speculations and numbers and days....
I am reminded that we all wear glasses..... we all bring our "worldview" and assumptions and paradigms with us. And today, that means a VERY physical, materialistic, scientific mindset. We assume numbers are just math without realizing that until recently, numbers were far more likely to have a non-math meaning, for example. People look at those Scriptures that speak of the FOUR corners of the Earth and argue there can't be THREE or FIVE and these must be 90 degrees (heresy to say 60 degrees!) and thus the Earth must be flat..... when individuals IMPOSE their mindset on others, absurdities can result.
