David Glass is a University lecturer in Northern Ireland. His book “Atheism’s New Clothes” critiques the arguments of Dawkins, Harris, Hitchens and Dennett. He says that, on the balance of probabilities, theism offers a better explanation of life and the Universe than atheism. James Croft works with the Harvard humanist community. He contests David’s use of probability theory. They discuss whether God is a good explanation for the fine tuning of the universe.
