I like this quote from Penn Jillete on the subject of the afterlife: "I'm not greedy. I have love, blue skies, rainbows and Hallmark cards, and that has to be enough. It has to be enough, but it's everything in the world and everything in the world is plenty for me. It seems just rude to beg the invisible for more. Just the love of my family that raised me and the family I'm raising now is enough that I don't need heaven. I won the huge genetic lottery and I get joy every day."
Given an infinite time and an infinite universes, there becomes a small possibility of existence again after death.
(I'm Christian, so I admit that I may be a bit more optimistic than is warranted)
