The difference is science can make you money, which makes it more important ( ) for children to learn so that they grow and serve their government better. Millionares look better on paper than religious humble types.
What, and religion doesn't make money? One word: televangelists. Those bastards make more money in a week than most scientists and engineers see in a year, for doing something that causes society to regress rather than advance. It's one of this age's ironies.

You've said that most scientific types are arrogant. That may very well be true, but it's wholly irrelevant. What is relevant is whether or not their viewpoint is well-supported and based in fact.

One may say that science is limited. Of course it is. We don't know everything yet. But the epistemology that underlies scientific inquiry is utterly flawless.
