Noah lived to be 950... — well, compare this to mythologies from Iran or India and you have people living for hundreds of years. Is it possible that climate change affected the length of a person’s life? Climate change post flood?
One of my kid’s just asked me that - about the long life spans.
My conjecture - with NO evidence to back it up - is that perhaps sin has grown with time, or each generation. Adam & Eve would have lived forever if not for their sin. And that original sin perhaps get passed down like those inbreeding maladies like the Kings and Queens of Europe had and things go from bad to worse.
So over time lifespans went from 900+ to 40-something(???) in the middle ages.
But with science, we are able to create cleaner environments, heal sickness, etc. - the life span has increased over the years in more recent history.
IMIAHO (In my ignorant and humble opinion!)
