These are all attempts to get around the plain fact that Eve did not die as a result of eating from the tree as God had said she would.
Think of it this way. You are a young woman whose mother is suffering from a particularly virulent form of cancer, all treatments have failed and you have been told your Mum has less than a month to live. However, there's hope! A pioneering oncologist assures you, promises you, that if your mother agrees to an experimental and untested new treatment she positively “will not die.”
You convince your still young but dying mother that this is her best hope. With nothing to lose she agrees to the treatment and lives on for another forty years! She’s with you at your graduation and on your wedding day. She’s a grandmother to your children and is even with you to enjoy a few years of your retirement. Finally, at a fair age in her mid eighties, your mother passes away.
Would it be reasonable of you to label as a liar the medical researcher who promised you four decades earlier that your mother would “not die”? After all, your aged mother is indeed now dead.
Preposterous isn’t it?
