Because from time immemorial people have asked this question. And the most interesting thing is that until we die, we will not receive the desired answer . It's simple, people don't want to believe that the life they have lived is all that is given to them. After all, the average statistical 60-80 years is so little. Those who have lived their whole lives quietly and modestly, like a true Christian (in no case do I want to offend believers), want to believe that after death they will be awarded a ticket to Eden for their obedience. And those who, on the contrary, burned their lives, but came off, want to hope that no punishment will follow.
Everything is much simpler than it seems. This curiosity stems from the fear of death. Death is not biological death of the personality, our "I", this is precisely the fear that helped the spread of the Abrahamic religions, for there is hope for salvation, for life, if not a shell, but "I" as a person. And so many people wonder if there is life after death.
Because it is natural for a person. We are afraid of death, because humanity has created many religions, so we are interested in knowing what will happen after death (more precisely, we hope that SOMETHING will be and, accordingly, we want to know what exactly). Now there is such a colossal number of theories about what will happen after death that I, for example, simply get lost, and at the same time I cannot know for sure which theory is correct. Accordingly, I am incredibly interested in which of the theorists is right.
