Is the soul of a human being created at conception by an act of God, or is it a natural creation, conceived from the beginning of creation? We do believe that part of identity is soul, which is separated from body at death, and that the heart is partly spiritual and the center of identity. So he would not be the same person by human nature alone.
I expect that one day people will be paying for the use of DNA of famous people to combine into their offspring. It will be a new genocide of sorts.
