On Biblical Inerrancy

Ken Ham is my straight man : Pharyngula: "If there was not one man Adam and one woman Eve, and a literal event of the one man Adam taking the fruit in rebellion and thus bringing sin and death into world, then one may as well throw the rest of the Bible away. It would mean what God wrote through Paul in 1 Corinthians 15 and Romans 5 for instance is plain wrong. If we are not all descendants of one man who sinned, then who are we, and why are we sinners?"
