The "Server In the Sky" comment cracks me up. It's a fitting parody.
Another, closely related question for JW's is: "What exactly was transferred from heaven when Jesus was born?" If it was simply a human body with the personality and memories of Jesus the spirit creature implanted, then what happened to the spirit creature? Did he continue to exist, or did Jehovah "Kill" the spirit creature so there wouldn't be two of them, one in heaven and one on earth. (I know this question sounds absurd to mainstream Xtians)
Further, if the human Jesus was born with the personality and memories of this spirit creature, it smacks of Frank Herbert's concept of the "Preborn" (Where a child is born having a fully developed personality, cognitive abilities etc.) but JW's reject this notion if I'm not mistaken and teach that Jesus memories were not fully restored until his baptism.
