"One thing that my friend espouses too is - the "fact" not a theory of devolution . That all living things will all die.
"

This shows a lack of understanding of the underlying science. Individuals dying has little to do with evolution, unless they die before being able to reproduce do to being selected out with a less successful phenotype.

The question that you should ask is - Why? It's not only human beings - it pertain to all - twig, tress, fish, grass, etc. They all die. You said this shows a lack of understanding of the underlying science. Can you name a single scientific experiment that challenges this fact? Doesn't science exists to prove the facts?
