Death Before Sin?

Q

I was watching a debate between a believer and an unbeliever about the young earth and old earth scenarios. At one stage they were debating whether plants died before Adam sinned.  The unbeliever argued that the Bible is wrong in saying that death only came into the world after Adam sinned.  His argument was that when Adam and Eve ate the plants, it killed them.   Would the dying of a plant be seen as death?

A

This is one of the many reasons I don’t like debates. The question of plants dying is irrelevant to the issue.  In Romans 5:12 Paul said,

Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all men sinned”

He was speaking about the fact that Adam’s sin brought death to all humankind.  (Adam and Eve had previously been immortal.)  There’s no indication from the Bible that plants and animals were created immortal in the first place.
