Science starts with observations. From the observations may come Scientific Laws, or detailed descriptions of physical phenomena. But science goes further than that. If a scientist can see connections, patterns and regularity, an hypothesis can be formulated to explain the observations. If enough data is gathered that supports the hypothesis, and experiments confirm the idea, and no contrary observations can be found, a scientific theory is put forward.
Theories are the goal, the pinnacle, of science.
Creationism starts with the bible, a bunch of words printed on paper, and will not deviate from what is written. All data, observations and conclusions must conform with their interpretation of the bible, or be rejected out of hand. There is no observational fact imaginable which cannot, one way or another, be made to fit the creation model. As you can see, creationism is not science. Scientists are devoted to seeking out the truth, no matter where it may be, even if the conclusion points away from their original idea.
