The origin of the quiz is interesting. According to Snopes, it's the result of a lesson based on an "educational" video from the (truly loony) Answers in Genesis, the proprietors behind the Creation Museum, a truly glorious Kentucky-based shrine to, well, all that crap you see up there. Adam and Eve rode dinosaurs, the earth is 6,000 years old, radiocarbon dating is an abomination unto the Lord, etc.—oh, and they're building an ark, too. A Kentucky-based, dinosaur-having ark theme park, and that has the potential to be the most awesome display of technology used to rebut technology that you can possibly imagine, if they don't cheap out on us.
As their actual, let's call it educational efforts, Answers in Genesis provides study guides, videos and other materials teaching and/or explaining how to teach all of the aforementioned silly things—the "Were you there?" rebuttal to all of human history before their personal birth is one of their hallmarks, for example, and can be seen on page two of the quiz. So yes, there's really, truly a certain population of the country that teaches it to their children in lieu of actual science. Then those children grow up and are elected to Congress, so you can't say there's not a career path there.
