I think that most of us can remember being 'nothing' (this might be wrong), and it baffles me why people are afraid to die, which is simply returning to 'nothing'.
That’s a preposterous claim. You obviously can’t remember not existing. Memory is not magical, it is a biological process that records information during your life and allows you to reexperience it.
It's a boundary condition. I expressed myself badly.
EDIT: If you are a physicalist. Some people are not.
EDIT2: "The Truth" has nothing to do with whether one is a physicalist or not, but the interpretation of some various sub-sets of the facts inform various ... schools of thought.
