Greetings to you sir, You are right when you say everyone is entitled to their own opinion, and are free to express yours without offending anybody. A lot of people believes in the reincarnation about someone after death, reborn again into another form, it could be animal or another person's body; well as I said, they entitle to believe whatever they like but as a christian, we have our pointer which is the bible so that should be our guard, because that's the basis of our Christianity, so if it is not recorded there then it is not there. Best of luck
