"One speaks of "natural selection," as if nature were an actual, intelligent entity capable of such a feat, while the other acknolwedges an intelligent creator."
Again, your ignorance of the theory of evolution is exposed here. Natural selection doesn't assume any intelligence in the process. It is based on the random process of genetic changes through natural mutations. The ones that are of benefit, or at least not harmful, tend to persist in future generations. The harmful mutations tend not to persist.
Again, you can argue more effectively if you will take the time to understand the theory you're arguing against.
