1a. If there is uncertainty about when human life begins, the benefit of the doubt should go to preserving life.
Shouldn’t we give the benefit of the doubt to life? Otherwise we are saying, “This may or may bot be a child, therefore it’s all right to destroy it.”
1b. Medical textbooks and scientific reference works consistently agree that human life begins at conception.
Many people have been told that there is no medical or scientific consensus as to when human life begins. This is simply untrue. Among those scientists who have no vested interests in the abortion issue, there is overwhelming consensus that human life begins at conception. (Conception is the moment when the egg is fertilized by the sperm, bringing into existence the zygote, which is a genetically distinct individual).
