"Before I formed you in the womb I knew you, before you were born I set you apart," I think He's referring to our souls, our essences, not our yet to be fully formed brains. It is a chilling thought that His Jeremiah statement may not apply to beings that He did not form in the womb but that human scientists did.
We better quit ignoring these pressing moral issues, because we can be sure that science is not going to wait for us to catch up.
This whole thread is about the simple fact that we do not know the answers, and scientific advances are far outstripping the moral frameworks erected so far upon which these advanced must be evaluated.
Science divorced from ethics and morals is a danger to be feared more than most other things today.
This is one of the best statements on this thread. Scientists think that because they CAN do something, they MUST do it. In other words, they are trying their best to usurp the position of God. Only disaster will come of their efforts.
Another point - where there is life, that is the symptom of the presence of the soul. But the soul who might inhabit the cloned human (if they are actually able to do it, which I doubt) would probably have twisted consciousness.
