Really, because I'm a scientist. I have an A.S. In biology and am currently working towards my bachelors at UIC. All of my colleagues and I agree. Adaptation is a function of evolution. It works through the process of natural selection, and evolution is, most definitely observable, and also is applicable in many, many, fields of study, which is far more then creationism could claim. Also contrary to what you may think I am not an atheist and many of my colleagues are also not atheists so I can promise you we aren't teaching evolution because we have something against God. Now go bang rocks together or whatever it is you creationists do for fun.
