As for the matter of "which creation to teach", the United States is a Judeo-Christian nation, no matter how the secularists try to spin it.
It's not a "Judeo-Christian nation," it's a nation that happens to have the majority of its citizens as Jews or Christians. Only three of the ten commandments are part of American law (don't steal, don't kill, and don't lie), and they're no-brainers. I don't know of any other parts of the Bible in American law.
If you want to bring up the religions of the Founding Fathers, their religions are both in debate and wholly irrelevant to this question.
Even if it was a Judeo-Christian nation, that's no reason to teach something from Christianity to the exclusion to all other religions. If we're going to teach something purely because it relates best to the majority, we might as well exclude all of the stuff from history that includes black people, since the majority of Americans are white.
Besides, the Genesis acount of Creation is the only one to which there were made significant scientific investigation and modeling to demonstrate it scientifically.
What "significant scientific investigation" has been done regarding the Genesis account of creation? There's nothing to investigate, unless we can somehow find the Garden of Eden or something. Creation doesn't predict that anything should happen that we can then test.
Evolution is weakening Christian kids allover the world. IF they are told every day at school: "Evolution is true. The Bible is wrong", how do you think they are going to get to Sunday school and study the Bible properly?
Uh, what teacher says "The Bible is wrong" when teaching evolution? If there
is a teacher saying that, he or she should be fired immediatley. There is absolutely nothing in evolution that specifically says that the Bible is wrong. The idea that evolution should be banned because it's anti-Christian is ridiculous.
Kids can learn about the theory of evolution in school and then learn about the theory of creation in Sunday school. Unless you want Sunday schools to start teaching evolution, why should public schools teach creation? Creationism is a fundamentally unscientific topic and, as such, should not be taught in a science class.
