"Creationists -

What is the one hypothetical piece of evidence that would make you disavow your belief in the biblical creation story as fact?

If you can't state one, you have just proven the difference between creationism and science, because anyone doing science could list you a dozen or more hypothetical observations that would cause them to abandon (or seriously revise) any given theory."

You might be surprised to know that I know many creationists who would agree entirely with your premise.

In fact, I was just streaming an interesting theology program that was chiding the fallacy rampant in what he called "evangelicalism" to willingly accept the notion that there was no fact that they could run up against that would change their belief in God. It was his contention that faith can not be absent reason. He further said that there were any number of facts that, if he became convinced of their truth, would utterly and completely change his beliefs. I agreed.

Oh, and my birth wasn't an accident. That was my younger brother. My folks intended to stop at me. I try to remind my brother whenever I can.
