To better understand how young earth creationists think, you might want to check out their Temple to Ignorance, Kentucky's Creation Museum.
If you ever visit the Creation Museum you will learn:
* The earth is only 6,000 years old (good thing too, since the First Agriculture Revolution started about 4,000 years earlier; I know, the math doesn't work).
* The Grand Canyon was carved out by Noah's great flood (seriously), and;
* The dinosaurs and man roamed the earth together (documented by early episodes of The Flintstones, no doubt).
For the fun of it, The Simpsons did a pretty good job of going through the creationist position here.
