I agree that there is no need to work out what type of creationism because it would fail due to it's lack of evidence when a scientific theory, supported by evidence, is proven beyond reasonable doubt, no matter what type of creationism it was.
Cats don't evolve into dogs. They are different branches from a common ancestor. Maybe that is the misunderstanding ?
Macro evolution is, as I stated earlier, just micro evolution writ large.
IMO one can't believe in one yet deny the other because they are the same thing. Once you agree that mutations occassionally survive because they prove to be beneficial then you accept diversity in a species and the ability of a changing hostile environment to alter the species beyond recognition over long periods of time.
If one single species gets split up and one part has no connection with another, for whatever reason, then the separate groups cease to interbreed and so follow their own different individual evolutionary paths until the accumulated changes are such that they are clearly different but related species. This is surely straightforward/logical, and fossil records support this even if we don't always find every step along the way
So denial just boils down to an inability to believe, possibly due to spiritual or religious faith, and relying on a lack of human understanding of how all complex systems we see today could have evolved. But that is just down to the fact that we are still ignorant of every factual detail, and it is unreasonable to insist every i is dotted and t crossed before grudging accepting the most likely, most supported by the evidence, explanation. If one must have faith, and faith is no bad thing, then save much of it for belief that our knowledge will expand, and in time fill in the minor details presently quibbled over.
