Phew. Bill, we were wrong to doubt you. We thought your inexperience in debates and of creationism, your lack of background in biology or geology, and the slippery dishonesty of Ken Ham, playing to a home crowd, would cause you an embarrassment. Not a bit of it.
You were superb. You stayed on message, you remained polite throughout, you were respectful of differing beliefs, and your natural charisma were too much for the nervous, repetitive and increasingly defensive Ham. The presentation of facts, pitched just right for the layman, was a continuous assault, not just on your opponent, but on the audience’s preconceptions of what science is, distorted as those are by creationism.
