Previously I explained that there are really two types of science.1 One is operational or experimental science which is based on repeatable experiments (e.g. done in a lab) in the present. The experiment can be repeated again and again, and because we trust that laws of nature (which God created in the beginning) are immutable we have learned to expect the same results. This is the basis of the modern technological revolution.
Historical ‘science’ is based on evidence available in the present but consists of stories about supposed events in the past that cannot be repeated, observed, or tested experimentally. It is forensic science where you have to make up a story about the past, which best fits the evidence at hand. The evidence is circumstantial at best.
If a moving automobile were an organism, functional biology would explain how it is constructed and operates, while evolutionary biology would reconstruct its origin and history—how it came to be made and its journey thus far.
