Can you give me a definition of a physical law? I think that might be our misunderstanding. I think we are talking about two different things.

I don't think we have even close to a full understanding of how the universe works. I think we have theories, that are either correct, or incorrect. Take the law of gravity for instance. It sure makes sense to me. I was taught it in school, and I just accept it as the truth, but what if it's wrong, what if it is basically right, but there is an exception to the rule.
You are right about that but the definition of theory is much different than most people take it as. For a law of physics to be a fact, lets take gravity for instance, it has to be proven to work in every instance possible. That means we would have to make sure gravity has worked in every instance and that is impossible so it impossible for some theories to become laws. But, out of millions of tests, there has not been one test that has even made a hint that the theory of gravity could still be wrong. We are 99.9999999% sure that gravity is right, there is a possibility that it is wrong, but that would most likely because of a unified theory and everything would be different when/if that happens.

As I said before, this perpetual motion machine is probably a hoax, but I don't think progress is made, by accepting what has been taught to us as absolute truth.
Yes, but there are no alternate theories to gravity or evolution that has any scientific backing so we can only teach one theory.
