However, is it the victims’ ages that makes the attacks wrong, or is it their humanity?
Clearly, whether a person is 50 years old, 18, or two is not what makes killing wrong. What matters is that the victim is human. Identifying the moment an individual person’s life begins also pinpoints when her human rights begin.
Science teaches us that a new human being begins at the moment of sperm-egg fusion, otherwise known as fertilization. Sperm and egg, by themselves, only contain half the genetic material needed to form a human being. When these cells fuse, however, a new individual who is genetically distinct from both parents comes into existence. There is a wealth of testimony from medical texts which backs this up.
