Science isn't committed to any "belief". The theory of evolution has changed many times over the years, all because the people who are qualified individuals in the field are not committed to a belief that any of science is absolutely true. Science has no absolutes, and theories can change as new evidence emerges.
If evidence emerged that contradicted evolution, it would destroy the theory. Currently, no evidence has ever been brought forward that has done this. All attempts by creationists are refuted when studied closely; this isn't because scientists want desperately for evolution to be true, but because the evidence brought forward is either wrong, misinterpreted, or simply the result of bad science.
Yes, the idea that God changed the natural processes throughout time is unfalsifiable, as is the idea that the entire universe was created Last Thursday (which I believe sincerely), and all memories and evidence for an "old universe" is simply fake. The point is, science is built on several foundations; one of which is falsifiability. That is, if something cannot be demonstrated through empirical experiments to be wrong, it cannot be placed into the realm of science. This is the single biggest reason why creationism is not accepted as an alternative scientific theory to evolution; like Last Thursdayism, it is unfalsifiable, and therefore no different (in science's eyes) to any other idea that is thought up on the spot.
