Some people apparently think theyll exist forever, that there is some kind of afterlife. Why?

Actually, two questions: why do you believe this, and why do you want to exist forever? I'm actually glad that blissful oblivion awaits me at the moment of death. I don't want to live forever; one lifetime on this earth is enough for me.

I will of course admit that I don't know what lies beyond this life (if anything), but for my own personal reasons I don't like the afterlife concept. Or reincarnation, although in the case of reincarnation at least your previous life is completely forgotten and you get the chance to live again, and maybe make better choices.
