I might get in trouble for this but oh well.. I think its an interesting topic.
I guess I just try to think logically about this. I'm not religious, so I don't particularly believe in afterlife. However, I do find it interesting that scientists have a theory on multiverses. Multiverse is a theory that more than 1 universe (our known universe) exists. With that said... is it logical to think that if multiverse did exist, you would never truly die? You exist on multiple universes with different outcomes and different events.
Example: In this universe I am married with a son and will likely die of old age. However, lets say in a parallel universe I exist but I never get married, never have children, and die of a car accident.
This is all just theory obviously, its just fun to talk about.
