Yes, ID, biblical creation, and evolution are all belief systems. They happened in the past and cannot be observed. We have evidence in the present that is interpreted based on the worldview (paradigm) that we bring to the table. I believe in biblical creation and I think the evidence fits better with a biblical model.
The “facts” of evolution are nothing more than man’s interpretation of the evidence. He sees what he wants to see based on his worldview. I have seen scientists with the same evidence draw different conclusions because creation and evolution can’t be observed, tested and repeated. All we can do is examine evidence in the present of things that happened in the past.
Evolution is a theory (in the scientific, not common, sense of the word). ID is also a theory, albeit a lousy one. Biblical creation, on the other hand, is simply a myth...one which is part of a belief system, granted.

What else should science use but evidence?

When Hubble looks at a galaxy 8 billion light-years away, it's looking 8 billion years in the past. Are you skeptical of theories of galaxy formation and evolution as well?
