Yes the level of argument leaves a lot to be desired, seeing as it is by an academic. He seems to be saying that the scientific theory of evolution requires atheism, which will come as a surprise to the numerous scientists around who have religious beliefs. P.S. Just seen spidergoat's reply which is more thoughtful. Certainly the theory of evolution does not imply any teleology, nor does any theory of science. But plenty of religious people are able to superimpose the teleology of their religions on science without it affecting the theory in the least.
