I don't believe that creationism (Intelligent Design) is all that bad for the scientific development of society. After all look at Issac Newton's list of accomplishments!
Newton is a great example. He did some marvelous physics when it came to celestial bodies. Beautiful physics. However, there came a point where he couldn't explain certain motions, he was stymied. So, that's where his quotation kinda comes from, he explained the parts that he couldn't explain with 'angels do it'.
Luckily for us, within ~100 years someone built upon Newton's work (stood on the shoulders of giants, for sure) who then explained all those unknowns that stymied Newton to the point where he said "God does it".
We see that over and over in science. There are a lot of instances where a spiritual explanation seems best and so people use the spiritual explanation. However (I've personally seen it over and over) there actually was a physical explanation for the event, and the people just couldn't see it. Usually because they stopped looking.
