Since there was some initial confusion and since there are those who mangle numbers to attempt to show otherwise, it is sometimes necessary to invoke the obvious. Apparently, you don't understand it or you wouldn't infer that creation by God is a natural process. Those are mutually-exclusive terms. Man does not create anything by invoking the supernatural or by violating any laws of nature. He is merely the catalyst which causes things to happen more quickly than they might otherwise happen.
Cattle are natural, and airplanes are man-made.
However, we can intervene in natural processes, through selective breeding, and produce pure-bred Angus cattle. Such a thing would not be impossible for an all-powerful God. However, that presupposes that such an entity actually exists. If he does not, then the question is pointless. Just because you suppose the supernatural and the natural to be mutually exclusive doesn't mean the former cannot affect the latter.
