No description of the afterlife given by any of the major religions appeals to me, save perhaps Buddhism from a mystical standpoint. If we want to start conjecturing beyond what anyone says the afterlife is like, then why believe in it at all? Without evidence, the only thing any of the religions claim to have going for them is holy books and priests claiming divine knowledge. If you want to ignore those, then you're just pulling ideas out of thin air. It might be nice to imagine some utopic afterlife for each person, but it has precisely the same relationship with fact as my desire to drop into the worlds of books I read and take part in the story.
I like to think there might be little racism and infanticide and much discourse on creating universes.
