Might as well present my own theory on this, since most evolutionists here think I am "full of it" anyway (can't hurt much more than that).
There are of course more than one theory floating around about this (and perhaps more than one factor is involved), but I have recently been concentrating on the one relating to DNA damage due to cosmic rays.
So, in brief, it may be that the accumulation of cosmic ray damage over a person's lifetime is what causes people to age.
NASA is concerned with such damage that will affect astronauts travelling to Mars, outside Earth's protective shield that deflects a portion of the damaging cosmic rays.
We have direct measurements made over the past 150 years or so which tell us that the magnetic field of the Earth has declined by 10% over that interval.
Did a stronger Earth magneric field in the past allow people to live much longer?
The Biblical geneologies might be interpreted to give a positive answer to that question. :chuckle:
