Your posr did not cause me dismay because I do not take literally the creation story in Genesis.
If I did, I would be dismayed because your point about death being necessary to evolution does appear to conflict with what you say is the biblical implication that death is the result of man's sin. So I can see how that would be a conundrum.
However, I note that Genesis 3 22 (King James Version) has the following passage: "And the LORD God said, "Behold, the man has become as one of Us, to know good and evil. And now, lest he put forth his hand and take also of the tree of life, and eat and live for ever"
This verse pretty well indicates that Man was never intended to be immortal, and therefore, that death is not the result of original sin.
So upon further reflection I'm not sure that your point is all that valid from a strictly Biblical perspective. (But what do I know? I'm not a Christian or practicing Jew. I'm just a Cemetarian, and certainly no Biblical scholar.)
