I think they will be waiting a very long time! If it ever did happen who knows what the consequences could be.
Just picking up on a point Memphis made about test tube babies. Made me wonder a little bit. About life begetting life and whether cells are living or not. They say life really only begins when a sperm and egg cell meet... becoming a new life. The egg cell and sperms cells quickly die otherwise. But even using the term 'they die' seems to indicate that cells are already living. Our body cells are continually replicating, renewing, dying so that the body is a different body (so to speak) than the one we had 7 years ago, apart from brain cells. However we are still the same person. So it just makes me wonder what really is life? And what is 'spirit'? Can it be recreated in a cell or in the whole person/creature?
