John.
1. Evidence exists.
2. The hypothesis of creationism attempts to explain the existance of all things.
3. The theory of evolution attempts to explain only the diversity of living organisms.
4. Since creationism attempts to explain more things that exist, more things can be used as evidence for creationism than things that can be used as evidence for the ToE.
5. Therefore, there is more evidence for creationism than evolution.
The problem here is the jump from "attempts to explain" to "uses as evidence." It's not EVIDENCE unless it SUPPORTS your thesis, John. It has to not merely be explainable by your thesis, but must be something we would EXPECT to see were your thesis true.
Hence, EVIDENCE for evolution is the existance of transitional fossils - Were the ToE true, we would EXPECT to see transitional fossils. We do. Hence, the existance of transitional fossils is EVIDENCE for the ToE. (The same type of thing works in reverse, though not as well. Evolution predicts that we will NOT find furry fish with hair similar to that found on mammals. We find no such fish. This is evidence, but rather weak evidence, since such fish might exist and merely be undiscovered.)
In the case of creationism, it's a whole different deal. If your hypothesis is "God created the universe and everything in it," you cannot make specific predictions about what we would expect to see were your hypothesis correct. Would you expect to see fish? Well, maybe. Would you expect to see furry fish? Well, maybe. Hence, the existance of fish and non-existance of furry fish is NOT evidence for creationism.
