A fetus is a developmental stage. Science classifies it according to species and all fetus are alive according to the scientific definition of what is alive. So, a dog fetus is classified as a living being and so is every other type of fetus including human. Therefore a human fetus by meeting the definition of being alive is a human life.
Abortion is state sanctioned termination of a human life. To say science in quotes like you can alter basic scientific knowledge is to bend truth to belief. An abortion ends a human life. Thats what termination means. So have an abortion, but dont lie about what's actually happening.
The human life is declared invaluable by both doctor and patient and that life is ended permanently which is death.
