Well said. The reason anybody calls scientific theories "laws" is because there is a big difference between what the word "theory" means to a layperson and to a scientist. Laypeople often use the word to mean a guess about why something is happening. If it is proven, the layperson does not call it theory, he calls it fact. But in science theories often have huge mountains of evidence supporting them, and we can be almost certain that they are fact. Creationists like to use the argument that evolution is "just a theory", implying to the layperson that it is merely a hypothesis about how species might have come to be. It is indeed a theory, but so is the idea that the Earth orbits the Sun.
