No one has proof? But of course there are those who have died (officially documented) and come back to life with accounts of what they experienced on the "other side"... so that would be proof as best anyone has, right? The problem is, just like with the original concept of a hell (versus a heaven or a place with God rather than absent of God) is that you either believe or you don't. It's one's choice... so to believe the accounts of those who have experienced and returned or to just believe without that...it's up to yourself.
