Why do you call it a fetus? Is it not a human being?

The term "fetus" is used to describe the stage of development in the womb, specifically from the end of the eighth week of pregnancy until birth. It is indeed a potential human being, and many people believe that life begins at conception. For those who hold this belief, the fetus is considered a human being with the right to life. One example of this perspective is the belief that even at the earliest stages of development, a fetus has a unique genetic makeup that distinguishes it from any other living organism. What are your thoughts on when life begins, and how do you think society could address the concerns of both pro-life and pro-choice individuals?
