Xotan-
Much as I hate to admit it, I live in a part of the Bible belt and I can assure you, I am no fundie. Want to know what cure me of believing any of that crap? I was dragged off to church every sunday until I was old enough to say "NO" and I have never been back.
One of the stunts I pulled (OK, two) was refuting the old Noah's Ark fables.
I simply asked this-
"So you're telling me that some guy, with no carpentry experience or access to power tools built a boat roughly the size of the QE2, travelled allover the world, collected 2 of every one of the billions of species on the planet, managed to cram them on this boat and float around for 40 days and nights.
THEN landed this same boat several miles up on a mountain, well above the level that would be possible if ALL the polar ice caps melted and all the world's water was liquid.
THEN set about delivering all these species back to their unique environments- even the oned that don't fly or swim and managed to keep them all alive while he was doing this.
THEN God put the rainbow in the sky as a promise to never flood the world again, implying that rainbows didn't exist until AFTER the flood. I then pointed out that rainbows exist because of a physics property called refraction, which is why eyes work the way they do and since most people in that time could see just fine, that's proof that refraction existed.
The second thing I did was this-
The preacher was getting flustered and asked me "Boy- what got into you?" (Don't ask a smartass like me a question like that- it leaves you open to all kinds of smartass responses).
You remember the guy from KISS with the freakishly long tongue? Well, I did my impression of him, along with the voice of the demon from the Exorcist and said this-
"My name is LEGION, for we are many!"
I did not know that a 300 pound woman in a girdle could jump hurdles (folding chairs) with such athleticism.
I was summarily banned from that church.
