Even if they happened to hold that, that is not evolution. Evolution is the change in gene frequency over time. It is a fact, because it can be observed. It is also a scientific theory. Evolution by natural selection. Because it explains why the gene frequency changes overtime. Edit - Also it is not random. Don't know why you think it is. It is guided by natural selection, something that is not random. If it was organisms would not be qualified for their environment lol
