Reincarnation is one belief to take and a good one at that. I think that it could exist the thing is there is no real proof and no way to find out either. Say a person dies would it and could it be possible for them to come back and speak to you again but in as a different person or thing altogether. I believe and it is my right that it is possible but then again that's just the kind of person I am there are many people out there that will try and prove that I'm wrong but I'm not exactly trying to prove a point only a 'theory'.
I'm not a christian either but that doesn't make anyone any different from one another, there are many different beliefs in this world it just depends on which ones that you believe to be true. For instance a person may grow up in a place where religion is considered something of high importance then they will try and take a path into the right one no matter what their inner feelings may be.
I don't believe in many religions but there are some people out there that do and that is their right just as all people have their rights in believing what they want and having their own theories about things it's just in human nature to be like this. Curiosity about the world after death isn't so bad and isn't wrong either just as normal as can be.
