Bosox - I'm afraid you misunderstand the word 'theory' when used in a scientific context.
Creationists often intentionally misuse the word when they claim 'evolution is only a theory' to laymen and you seem to have fallen into their trap.
Theory

The word theory has a number of distinct meanings in different fields of knowledge, depending on their methodologies and the context of discussion.
In science, a theory is a mathematical or logical explanation, or a testable model of the manner of interaction of a set of natural phenomena, capable of predicting future occurrences or observations of the same kind, and capable of being tested through experiment or otherwise falsified through empirical observation. It follows from this that for scientists "theory" and "fact" do not necessarily stand in opposition. For example, it is a fact that an apple dropped on earth has been observed to fall towards the center of the planet, and the theories commonly used to describe and explain this behaviour are Newton's theory of universal gravitation (see also gravitation), and general relativity.
In common usage, the word theory is often used to signify a conjecture, an opinion, or a speculation. In this usage, a theory is not necessarily based on facts; in other words, it is not required to be consistent with true descriptions of reality. This usage of theory leads to the common statement "It's not a fact, it's only a theory." True descriptions of reality are more reflectively understood as statements which would be true independently of what people think about them. In this usage, the word is synonymous with hypothesis.
