Theory: a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; "theories can incorporate facts and laws and tested hypotheses." Addendum: "Theories do not grow up to be laws. Theories explain laws." (Courtesy of VadeRetro.)
Hypothesis: a tentative theory about the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena; "a scientific hypothesis that survives experimental testing becomes a scientific theory"; "he proposed a fresh theory of alkalis that later was accepted in chemical practices"
Guess: an opinion or estimate based on incomplete evidence, or on little or no information
Law: a generalization that describes recurring facts or events in nature; "the laws of thermodynamics"
Assumption: premise: a statement that is assumed to be true and from which a conclusion can be drawn; "on the assumption that he has been injured we can infer that he will not to play"
Model: a simplified framework designed to illuminate complex processes; a hypothetical description of a complex entity or process; a physical or mathematical representation of a process that can be used to predict some aspect of the process
Speculation: a hypothesis that has been formed by speculating or conjecturing (usually with little hard evidence)
Observation: any information collected with the senses
Data: factual information, especially information organized for analysis or used to reason or make decisions
Fact: when an observation is confirmed repeatedly and by many independent and competent observers, it can become a fact
Belief: any cognitive content (perception) held as true; religious faith
Faith: the belief in something for which there is no evidence or logical proof; acceptance of ideals, beliefs, etc., which are not necessarily demonstrable through experimentation or reason
Dogma: a religious doctrine that is proclaimed as true without proof
Religion: (theistic): "1 the belief in a superhuman controlling power, esp. in a personal God or gods entitled to obedience and worship. 2 the expression of this in worship. 3 a particular system of faith and worship." Non-Theistic: "The word religion has many definitions, all of which can embrace sacred lore and wisdom and knowledge of God or gods, souls and spirits. Religion deals with the spirit in relation to itself, the universe and other life. Essentially, religion is belief in spiritual beings. As it relates to the world, religion is a system of beliefs and practices by means of which a group of people struggles with the ultimate problems of human life."
Impression: a vague idea in which some confidence is placed; "his impression of her was favorable"; "what are your feelings about the crisis?"; "it strengthened my belief in his sincerity"; "I had a feeling that she was lying"
Opinion: a personal belief or judgment that is not founded on proof or certainty.
Based on these, evolution is a theory. CS and ID are beliefs.
I have made the point on this thread that the theory of evolution contains faith-based beliefs (see previous posts relative to HOX gene mutations and feathered dinosaurs like Sinosauropteryx).
One can not construct an evolutionary model that takes a simple single-celled organism from a primordial soup to all the complexity and diversity observeable today without faith (belief in something for which there is no evidence).
It also takes faith to believe in any scientific "theory" associated with abiogenesis...specifically that it was only a natural event (unless, like Dr. Crick, you are a proponent of aliens as the cause, which also takes faith).
As for religion/philosophy...see Humanism, Naturalism and Materialism. The stated beliefs of these religions/philosophies are espoused all the time in what poses as science (especially around here...just look at some of the previous posts).
The basis for Materialist philosophy is matter in motion, with all things being explainable by the laws of physics and chemistry.
Secular Humanism (a religion as noted by the Supreme Court, Torasco v. Watkins) believes the following:
We are committed to the application of reason and science to the understandings of the universe and to the solving of human problems.
We deplore efforts to denigrate human intelligence, to seek to explain the world in supernatural terms, and to look outside nature for salvation.
We are committed to the principle of the separation of church and state.

It should sound familiar...These religous statements of belief are verbalized/preached in an on-going basis in connection with the TOE (again, especially around here).
