I assume you would accept science's explanation of the facts.
There is an official scientific definition of LIFE. It is why viruses are NOT classified as LIFE. You can find this definition in EVERY high school and college level biology textbook. At conception, the zygote meets ALL the qualifications to be defined as LIFE.
The zygote possesses 46 HUMAN chromosomes. Chimpanzees have 46 chromosomes, but they are not HUMAN. A genetic profile of the zygote would be classified as HUMAN.
Finally, there is a differentiation in cells from the mother. There is a clearly separate genetic profile in the cells of the zygote from the mother's cells. Therefore, it is NOT the mother's body, but a SEPARATE HUMAN LIFE.
I will make the following concession: birth control pills prevent implantation, so a strict definition of life beginning at conception would cause these medications to be classified as abortion drugs, and I'm not ready to do that. But once implantation takes place, I think the embryo should be allowed to develop.
You don't have to be religious to believe that abortion is murder.
