What opponents of evolution (and other theories) don't understand is that science is not about finding the truth (that is best left to philosophy professors) but about finding out something useful about this world.
The predictions of theories can be used in engineering and other fields. Applications of the theory of evolution have been used successfully in such diverse fields as medicine and (yes) computer science. Evolution is solid, a tool that we can use to advance.
For a good article about the difference between a scientific theory and Creationism and the utter stupidity (and, I want to add, sacrilege) of believing in "Intelligent Design", see Steven Den Beste's essay about the human eye.
http://denbeste.nu/essays/humaneye.shtml
The vertebrate retina is a terrible design. The optic nerve comes into the eyeball at a certain point, and the nerve fibers spread out across the surface of the retina. Each individual nerve fiber reaches its assigned point, burrows down into the retina through several layers of epithelial cells, and ends with the light receptor itself pointing away from the lens of the eye, which is the direction from which the light must come. As a result, incoming light strikes the surface of the retina and must penetrate through multiple layers of inactive cells and then through the body of the nerve itself before it reaches the active point where it might be detected. This both diffuses and attenuates the light, decreasing the efficiency of the retina in accomplishing its function.
For a rationalist and atheist like Steven Den Beste, extrapolating from the existence of the human eye to a "designer" is illogical, because there is no evidence for design but plenty evidence for evolution.
For me, personally, saying that the human eye has been "designed" is blasphemy. I do not think it is all right to claim that G-d would intentionally create a faulty design or was incapable of doing better. (Plus I agree with Steven's thinking as well. There is evidence for evolution in the human eye, but no evidence for design.)
But the problem here is not the fact that some people are not capable of understanding complicated science and are thus forced to make up fairy tales that make them believe that they are as clever as scientists (and even cleverer since scientists don't "know" the truth), but the fact that those some people sometimes have the power to take away knowledge from the rest of us.
There are MANY countries in the world where Creationism is taught instead of evolution. I wouldn't be surprised to learn that the majority of the world teaches Creationism to some extent, replacing biology or "adding to" biology in schools.
But what does that do for those societies?
Are they leaders in science based on learning something that is a "theory" just like evolution and a "better "explanation?
It's not enough to change the rules to allow Creationism (or "Intelligent Design") to become science, because what is science is not a decision made by man. It's ultimately a desicion made by nature (or G-d, if you will). Because science is something we can use to create.
When we look at the world and compare societies, we see that countries that teach evolution create technologies, whereas countries that teach Creationism, do not have the workforce to be leading in any field of technology.
Teaching Creationism causes stupidity. That's the problem.
And it doesn't help if "Christian" fundamentalists in the west blame Islam for it and pretend that teaching "Christian" Creationism will give better results, because the Creationism of Islam IS the Creationism of Christianity. It's word for word, letter for letter the same legend.
And it's phony. It's phony and stupid and a big lie.
* Why does the birth canal run through the middle of the pelvis?
* Why does the backbone run down one side of the trunk instead of through the middle where it would be more balanced?
* Why does the ankle attach at one end of the foot instead of in the middle?
* Why are there toes?
* Why is it that nearly every part of the brain is as far as possible from the piece of the body with which it is associated?
o Why is the motor control center for the right side of the body on the left side of the brain, and vice versa?
o Why is the vision center at the rear of the brain, as far from the eyes as possible -- and on the opposite sides?
* Why is it that fully 90% of the genetic material we carry around is useless?
* Why do we share a single canal through the neck through which we both breath and swallow?
Biology has explanations for these oddities. Creationism does not. "It was G-d's will" is not an explanation, it's an excuse for incompetence.
(Why are some people born with a mechanism that destroys the beta cells in the pancreas, causing Type 1 Diabetes that is ALWAYS deadly within a few months without treatment? Would an "intelligent designer" design his subjects like that?)
Richard Dawkins called evolution the "blind watchmaker" because evolution does not "see" what it produces, it merely tries out what happens with the stuff it finds. I find the term "incompetent designer" appropriate for a god who designs things like us. And I cannot pray to an incompetent designer. How could I?
Teaching Creationism has never helped a society and is bringing down many.
Dear Creationists,
I do not want the western world to become a second "Islamic" world.
Do you not understand that?
