Nobody has risen from the death. So it all depends on what are your beliefs about life in general? Do you believe in religions and do you follow them up? Or you are reading some ancient myths and try to figure it out from there. Nobody knows this answer for sure, if you ask me -- I think that there must be something simply because if there wasn't then life here is pointless and I think that we are here to learn and experience some things. This question is sure one of the toughest ones to answer.
I've read some books on NDE or near death experience wherein those who claimed to have died and returned back to life tell story about their experience when they were out of this world. I mean when they went out and left their physical body here To the other world. They tell stories like they've been to hell and then they been to heaven also and the site of this and that and the feelings they experienced while they were there. Sometimes i wonder if this people are telling based on experience they have or just making up stories. Sometimes it interests me to read more.
In Islam there is life after death. That is, life after death is like in the grave and in the hereafter. Which in the hereafter all our good and bad deeds will be weighed and counted. Then after that we will be put into heaven or hell,🙏
From your story, that when they were in suspended animation and saw heaven and hell. most of them after seeing heaven and hell, they changed into a better person than before 🙏 and the story is true.
That's what I know
