While naturalists and evolutionists claim themselves to be scientists, they hold on to the anthropic principle for dear life. The anthropic principle which basically says that the Universe exists because it exists is the exact opposite of science. Science is about 'how' and 'why', it is about causes and effects. The anthropic principle just says that existence is proof of materialism when of course it proves no such thing. All it proves is that they have no rational explanation for their statements.
That pretty much sums it up. One of the big complaints about intelligent design theory is that by saying "God did it" research comes to a halt - so instead, when a fact which points to design is found, it is placed in the "anthropic principle" bucket and research comes to a halt. Ironic.
Ian's Cosmic Matters has an interesting collection of these in layspeak.
