Objection: Genesis 9 mentions "blood" — does that mean life only begins when blood forms? No — blood represents life (used in Levitical sacrifices, "cleansed by the blood of Christ"). But even if you took it literally, blood forms at day 21, making virtually all known-pregnancy abortions murder.

Blood in Scripture represents life; it's not a starting point for life. Used in OT sacrificial system and NT theology of atonement. Even on the literalistic reading, blood forms at ~21 days (before most women know they're pregnant), so the argument backfires. Mike shares a story of a family member whom he convinced with simple repetition of "thou shalt not murder" — years later that person repeated it to others.
