Rebirth as a metaphor for a change in beliefs and lifestyle? Sure. Literal reincarnation? No. Well, in the sense that the atoms of our bodies will eventually be part of other living things, yes, but not in a spiritual sense.
If we are spiritual beings then we must have come from somewhere and go to somewhere and be working on achieving something. That's what I think. I'm not going to go into the mechanics of it in terms of reincarnation though.
Growing up in a buddhist country, I leant a lot about rebirth. My first novel 'Butterfly Kisses' though fiction is based on the concept of rebirth . As to whether I believe it or not - it never was a question!
I never used to but am a believer in Neale Donald Walsch's teachings in his Conversations with God books which are common sense and believable and fearless. Neale Donald Walsch was deeply inspired by the message that "the purpose of life is to recreate ourselves anew in the highest version of the grandest vision we ever had about ourselves." and has written on the subject of re-birth.
