Oh, you misunderstand: I have known people who have never died, as far as they know, but I cannot remember, now, whether there was ever a time when I did not know anyone who had.
A surprising number of creatures -- roaches, rats, birds, all kinds of domestic animals and more -- used to be people once. Yet also many of them have no souls at all, and I am not sure there is really any way to tell for sure. There really is no sense to it at all, or I'd have succeeded in orchestrating a demise for myself more permanent than nature has yet managed. Apparently Fate alone knows what's going on around here.
