I figured I would put my two cents into this one.
Of course evolution is a theory, just as is any other scientific discourse or theological discourse or otherwise. Christianity is, by an large, a theory and a theoretical framework of hypothesis and secondary hypothesis. The same goes for anything in physics like relativity or mathematics (which is not a science in the classical empirical sense, neither is theoretical physics for that matter - Einstein was a philosopher, or a natural philosopher in the classical sense, rather than a modern scientist).
However, what the original poster is attempting to do, and what the debate between creationism and evolution is marked by is simple: a demarcation theory or assumption between science and pseudoscience. This is actually a problem in the philosophy of science, and it has to do with seeking a demarcation criteria between what is scientific and what is pseudo scientific. The classical or common line of argument is that evolution is a scientific theory, while creationism is a pseudoscientific one. However, I would like to warn against this and perhaps look at some philosophers like Feyerabend. It is more difficult than one think to demarcate between scientific theories and pseudoscientific theory, Kuhn proved as much. Lakatos attempted to demarcate between progressive and degenerative research programs, but this has its problems as well.
Generally, the demarcation between science and pseudoscience is a problem that has not been solved yet in philosophy. Without solving such a problem this debate will never get beyond superficial and rhetorical argumentation.
End of thread.
Note: ^Vampan, you make a lot of errors in your post that have to do with a confusion about metaphysics. You are begging questions in a way that makes them illogical given a specific metaphysical framework, like say 'god'. Asking 'who created god' is an illogical proposition that would beg an illogical answer because you are confusing two levels of metaphysics and epistemology. A Human being can beg such a question, granted, because causality and origin are frameworks of human cognition. Experience, then, must be structured in such a way. 'God' however, is a proposition that is beyond the bounds of human experience, and thus beyond the bounds of the 'logical' and perceptional rules given by human cognitive structures. But affirming its negation, i.e. NO God, is affirming the same type of metaphysics as the former. In this way, atheists are doing the same thing as deists or theologians - however atheists tend to confuse their metaphysics and, thus, believe their proposition 'no god' or the negation of god is logically sound or a proposition consequence to inductive logic and empirical phenomena (induction from observation is an impossibility by the way).
Do not think your are above theologians, nor think that your simply comments are enough to prove some sort of 'infinite regression' making the proposition of God's existence false. You've done no such thing, all you've done is confused your metaphysics and, thus, begged the affirmation of propositions that are beyond the bounds of logic structures.
