ID is set up to fail if you look at it a certain way. If there is an intelligent creator, how can you *test* that through experimentation? You can't turn God into a variable or a constant in a lab.
It's like trying to prove that stone henge or the pyramids were designed/not designed.
ID people also go to the "God of the Gaps" argument, simply going to a spot in science where we are not sure (i.e. say, the origin of the universe or crazy theoretical physics) and say "See? Scientists can't figure it out! It must be God" That's somewhat of a copout and its also setting yourself up for failure as well.
Once we do figure out the mathematics or physics behind a previously unknown theory, then the ID person would just cop out again and go to the next "gap" in science.
On the other hand, just because you believe in a creator doesn't mean you have to disregard science all together. That's like saying "well, the Mona Lisa was intelligently designed, so we don't need to analyze it anymore."
How stuff *came to be* can be argued, but no matter what you believe, you can still look at and analyze how stuff *works* and appreciate the physics and mathematics behind it.
