ID is the theory that things are intelligently designed. Like the computer your using or the car you drive didnt evolve on their own, but were specifically designed by an intelligence. That kind of theory is applied to life and the universe.
OK, here is your chance. Explain ID in such a way that it can be a theory.
First, you must understand how the term "theory" is used in science. It does not mean "my best guess" or "an idea." In science a theory is along these lines:
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. Theories do not grow up to be laws. Theories explain laws.
Theory: A scientifically testable general principle or body of principles offered to explain observed phenomena. In scientific usage, a theory is distinct from a hypothesis (or conjecture) that is proposed to explain previously observed phenomena. For a hypothesis to rise to the level of theory, it must predict the existence of new phenomena that are subsequently observed. A theory can be overturned if new phenomena are observed that directly contradict the theory. [Source]
Since ID claims to be a science, it must adhere to the rules and methods of science.
So, here is your big chance. Explain ID in such a way as to qualify as science using the rules and methods of science. [But be cautioned that ID has already been determined by a federal court to be religion (Dover).]
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
