As a proponent of evolution its alot easier for me to imagine evolution occuring, then a "god" creating(poofing) everything into its current state. I see change in everyday life. I see how people change over time, life itself is about change. People and their understanding of things evolves over time.
I like complexity, not the simplest answer possible. In the case of how the world came to be the way it is today, ID in the form of christian creationism, is about the simplest explanation there is. Now if you came to me and said "God created evolution and thats is how he creates an endless supply of life to populate the earth". I would probably agree with you. He may have set everything in motion, but after that has let his creations run their course.
Why not try to imagine that god created evolution(yes god created evolution!!!!) so that life could adapt to different conditions on earth?
I think that something created everything, but it just set the basics in motion and then left the universe to itself.
I do not really disagree with ID, but its based on religious ideals for the most part. Most religious ideas are for the most part wrong about how the way the world is today. Even the catholic church eventually accepted that the earth wasn't the center of the universe. Eventually fundametalist creationists will see the light and accept that the world is very very old, that evolution is how life evolves and changes when faced with different climatic conditions and food sources.
