Some people here are saying that reincarnation can be true or else we would always have the same amount of people. Somebody would need to die in order to be reincarnated and have another person be born. I think that the thing is that many people who believe in reincarnation believe that you could be reincarnated as a different species. A human could become a fly in another life. A cow could become a human. I don't really know much about reincarnation and therefore don't believe in it. I have heard some strange stories though. Some people have claimed that they can remember their previous life. They have been able to find information about their previous selves and remember many details. I don't know if their just hoaxes or not though.
