Before you can even answer the question of whether or not abortion is moral, you must first decide what the unborn is. For as Greg Koukl of Stand to Reason observes, if the unborn is not human, then no justification for elective abortion is necessary. It would be no different from having a mole removed or a tooth pulled. But if the unborn is human, then no justification for elective abortion is adequate.
If it’s true that no one can tell when human life begins, then the benefit of the doubt should go to life. We should not be aborting the unborn because there’s a chance we could be aborting living human entities. If a hunter hears a rustling in the woods, does he shoot right away or does he make sure the rustling wasn’t caused by another human? Or if you’re driving down a road in the dark and you see the outline of something that may be a child or may simply be the shadow of a tree, do you drive into it or do you slow down? Or if you’re about to blow up a condemned building and you’re not sure if someone’s inside, do you blow it up anyway or send someone in to make sure?
However, it’s not true that no one can tell when human life begins.
The unborn from fertilization are alive because they exhibit the properties of living things. They grow through cellular reproduction and division, they metabolize food for energy, and they respond to stimuli. In fact, the only things the unborn need to survive are adequate nutrition, a proper environment, and an absence of fatal threats. That’s all any of us need. There is no point in human development at which the developing entity goes from non-life to living.
