Intelligent Design vs. Evolution

ok, so for quite some time the controversy between evolution and the church has been evident. And there some people are debating whether intelligent design should be taught in classrooms as an alternative to evolution. I myself think that it should be just to show kids that evolution is not necessarily true and that another theory is there too. I'm not sure whether I believe in intelligent design or evolution. Both arguments are convincing and have strong supports. So here is what I think of both:

Intelligent Design is basically the belief in Creationism, God made everything here on Earth exactly the way its suppose to be, and everything works perfectly together because of God. For example, when we breathe out it produces carbon dioxide which helps trees live; and trees turn that carbon dioxide into oxygen which helps people live. Evolution is a theory not a fact, and "the complexity of an organism is evidence for the existent of God." God created the complex systems so that they'd only work if all components work together at the same time. 

Evolution is technically states as change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift. This  contradicts intelligent design, because that means that God didn't create Everything. It means that we learned to adapt to our surroundings and there are several alternatives such as natural selection and the big bang theory that provide answers to how the world came to be, rather than God created it. By saying God created it, means that we are having blind fate because we cannot prove that he did or did not, there is no record of it. Basically intelligent design cannot be proven by an experiment, therefore it is not legit.
