I'm stating that there is no evidence whatsoever that the morphologically diverse Cambrian fauna arose via natural selection. If they had we'd see fossil evidence of the ancestors, branches etc. Now tell me why should I believe they evolved without evidence? isn't that called "faith"?
Appeal To Belief
One must believe there is absence of evidence for fossil evidence in question. One must believe you understand or read about natural selection. One must believe you are not arguing based on faith.
The existence of scientific law is itself evidence of creation. Laws of nature, matter, energy, fields are all evidence of creation for how else could these things have come to exist? Whatever brought these things into existence is what I term "creation".
