The Unborn are Human Beings:

First, the unborn are human beings. Somewhat ironically, it is science that tells us that the unborn are human beings.  From the moment it exists an entity has being.  And from the moment of conception an embryo has human DNA, he or she is the product of two human beings and thus is a human being. 

Some will object that it is “just an embryo” or “just a fetus.” However, look up the terms in most medical dictionaries and you will learn that among humans an embryo is a “human being from conception until the seventh week of life.” While fetus - derived from Latin for little one - refers to a human being from the eighth week of life until birth.  Therefore, referring to the unborn as a fetus only describes the stage of development of a human being. To deny that the unborn is a human being is to deny biology.

Another objection is that sperm and eggs have human DNA but we don’t consider them “human beings.” Author and apologist, Trent Horn addresses this: “Sperm, egg, fetuses, and toddlers are all human in the adjective sense of the word, since they possess human DNA. Unlike sperm and egg, however, fetuses and toddlers are also human in the noun sense of the word. A fetus is a human and a toddler is a human, while an individual sperm cell or egg cell is not a human. This is similar to how we might say apple pie and the president are both American, while the president of the United States is an American, and the apple pie is not.” ¹
