Personally, and I'm not saying this to start an argument - it's just the way I feel, I think that believing in the afterlife and the idea of any kind of immortality is egotistical. Those ideas were made up, I believe, a long time ago to ease the minds of people who had hard lives. Be good, love your neighbor, persevere and you'll get a heavenly reward.
I'm a good person, I (sort of) love my neighbor and I persevere. When I die, though, the gig is up. I'm ok with that. I harbor no illusions that anything magical will happen when my time is up.
