KM, you commit the fallacy called "misplaced burden of proof." You are the one who asserted that the Bible has nothing to say about the unborn. It's your job to prove it.
We don't need to concern ourselves with what ancient Greeks thought. Everyone who has taken a high school biology class knows that life begins at conception. Perhaps you're still in junior high school and haven't gotten to that lesson yet. Borrow one of your older siblings' biology textbook and have a look.
