I sympathize with your problem. But the problem is, you have confused creationists with theistic evolutionists! They are the ones that say that evolution occurred, but God guided it. He didn't. He created EX NIHILO, from scratch, in the beginning (that's pure creationist thinking; theistic evolution is merely a compromise position by those who have departed from their Bible). For a view of what creationist biology might actually look like, I suggest you start here. I believe you will find it quite interesting:
