As a test to the validity of this belief, I challenge you to tell me about something that is genuinely empirical in nature that creation scientists and evolution scientists disagree about (that necessarily implicates their opposing positions about ultimate origins).
This is actually an easy answer. Creationist assume the Bible to be correct with respect to species diversity. If data conflicts with their interpretation of the Bible they throw it out and claim they must have done something wrong. Through this process they have thrown out almost all of their data. Evolutionists believe the data is correct and use it. Creationists use inductive reasoning in that they assume Creation without prior evidence and then look for anything at all to back it up, even if it is easily refuted. In evolution, it was the data that brought about the theory, and still supports it. This is deductive reasoning. Quite simply, creationists use inductive reasoning and evolutionists use deductive reasoning.
Perhaps the question to you is what evidence is there to assume creationism as fact?
Also, simply saying some scientists use evolution to further political goals does not make the theory incorrect.
