Well, you must remember that scientists do not "prove" theories, they can only disprove them. Quantum theory, the theory of relativity, etc are also all theories that are not proven (in fact we have good reason to believe that they are incomplete as written). We can say that they are consistent with the data, and that so far they have been successful at predicting hithero unobserved phenomena. However, there may be other theories that provide the same results up to a certain point (e.g. string theory). If they can be tested they may replace the old if they are more successful. Such a thing cannot be ruled out, which is why direct proof is never possible. On the other hand if a theory fails the test of prediction, then it is clearly wrong.
A theory in the scientific sense is an explanatory framework for a set of observed facts. It is testable against reality, and offers predictions about what we should see in nature. In this sense evolution is a scientific theory since it has successfully withstood the tests of time and nature.
Intelligent Design (ID) is more problematic as a theory because of its lack of precise definition, as well as explanatory/predictive power. If one labels ID as the idea that "irreducibly complex" structures/behaviours cannot evolve (which is the typical def'n), then one is out of luck. This is an argument from incredulity and is not scientific at all. Saying that complex systems must be designed is a worthless statement without an adequete, quantitative def'n of complexity or a means of testing the same. This view of ID is however, utterly marginal in the scientific community and so has no currency amongst researchers. In any event the central tenants of this theory have been shown to be incorrect both by biologists and computer scientists.
However, if one abuses the terminology one can think of a weak form of ID, which perhaps better termed 'Theistic Evolution'. This, as its adherents will agree, is not a scientific position, but rather a theological/philosophical one. Essentially, it recognizes that the general theory is correct but still admits a role for God either through direct intervention (fiddling the dice so to speak) or His action through secondary causes. This last variant is reasonably common although noone will hold that it is at all a scientific view.
The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes. Taking this point of view, we may conclude that science is not physics, biology, or chemistry—is not even a "subject"—but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning.

Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that my ignorance is just as good as your knowledge
