Hmm... I don't mean to discuss your beliefs, but I'm a bit puzzled at your choosing the fact that all people die (as do "animals," btw) as even one reason to believe that the Bible is anything special.
My point is that, given the ingenuity of man and the unpleasantness of dying, if the death sentence wasn't an edict from One capable of enforcing it, someone would have found a way to avoid that sentence. Not that none have tried.
