Lifespan 1000 years to 80?

[Gawdzilla]

Mega hoop jumping to try and rationalize the goat-herders' campfire stories. 

You can understand their need to explain these impossible bible stories to themselves. They know full well that men didn't live for hundreds of years but they cannot possibly admit that the book is a myth or else the OT just unravels. That only leaves one possible recourse - massage the myth to fit reality, in this case adjust the length of a year.

I've never met a believer who bothered with explanations. There must be some, I just don't know any. So I can say that I don't understand that "need", because I really don't think it is relevant.
