One counter-argument I can anticipate from creationists is that they accept microscopic but not macroscopic evolution. I don't see how one can be separated from the other myself, but as I say I'm not an expert.
The only difference between micro and macro is degree, and there are no inherent barriers between them. Basically the classification is arbitrary. I could just as easily and arbitrarily define "micro-walking" as walking to the end of my driveway, and "macro-walking" as walking to the end of the block. Alternatively, I could define "micro-walking" as walking to the end of the block, and "macro-walking" as walking across the state. The processes to accomplish either are identical, and there are no inherent barriers between them, though the condition of the environment may affect the paths taken en route to the destination, and even which destinations are reachable vs. unreachable.
Macroevolution - proven beyond a reasonable doubt.
Microevolution - proven even beyond creationists' doubts.
