What is Science?

A better definition of science might help clarify the science vs. religion debate. Here goes.

Science is a concise language system for making consistent statements about the universe.

Consistency in formal language theory means that only true statements can be generated and that the language cannot generate a statement that true equals false. Since truth in science is tied to observation and experiment, the axioms of the language must survive empirical scrutiny. The limitations and complexities of observation and experiment add uncertainty to science and give job security to scientists who continually try to make science more consistent. Guidelines like Occam's razor help to ensure a concise language by advising parsimony.

Gödel's proof says that a language cannot prove its own consistency, nor can it make consistent statements about things not in the language. This means that science cannot make consistent statements about a possible meta-universe or God; it can only make statements about things having empirical support. Science is limited to statements that can be generated from its axioms and are thus tied to empirical truth.

If God violates the laws of physics with revelations, prophesies or miracles, science can only observe that there is some evidence of these exceptions. Those who believe the Gospel accounts see them giving at least some empirical evidence for such exceptions, whereas others believe that violations of physical laws have never occurred. The intelligent design motivation is to look for empirical evidence for these exceptions.
