The ancient Greeks and Romans also routinely killed their children in utero so your definition of "person" is clear overreach and not in line with historical facts. The Spartans would even throw unwanted children over a cliff or leave them exposed to predation because they had not earned personhood yet. The Romans found an abortifactant plant and literally picked it to extinction aborting unwanted children. There have always been abortions and there always will be. Having babies is dangerous, even in the best of circumstances. Women will do what they need to do. Outlawing abortions and birth control will not stop abortions. It will only increase them. Your be surprised how easy it is in the modern age to get rid of an unwanted pregnancy. It's just not as safe.
