"Actually, it doesn't require death. All that it requires is that the individuals with "inferior" genetics be unable to spread them. A creature that lives for 3000 years but never reproduces during its life is an evolutionary dead end."
But a creature that can not die will still be around if it can reproduce or not. Bottom line is that we see no immortal lifeforms around today, so by evolution there have never been any around. This is contrary to the fall as recorded in the Bible again showing the two ideas are not compatable.
Along these lines, it would have been a LOT easier (Evolutionarilywise) if critters continued to STAY alive and NOT die, than to EVOLVE a way to reproduce to KEEP from dying!!!
Just how many times did 'Life' emerge from the muck, just to find out that there was a brick wall coming:Death.
Damn! Now what do I do?
I guess the next time I spring from the ooze, I'd better have a PLAN to git me some little 'uns!
