BB, many people will disagree with you as to when life begins. It certainly isn't at the moment of conception. At the moment of conception there's not much difference between a fertilized egg and a cancer cell. Perhaps you could argue that it's at 6 or 7 weeks when you can detect a heart beat...but even then the brain and the rest of the organs haven't formed, so is it really alive then?

In my opinion a child is not a child till it's developed enough to live outside the mother's body on it's own (roughly around 26 to 28 weeks), before that it's an extension of the mother's body.
