William Lane Craig gives one of his best presentations on evidences for theism. It is directly aimed at the heart of atheistic arguments and destroys many of the straw-men placed by said atheists.
There is a short follow up by atheist professor Daniel Dennett that lasts about 10-minutes or so, who has no defense of his atheism in light of what just happened. He basically mentions that his non-knowledge will some day be filled in (atheism-of-the-gaps). Professor McGrath (theist) finishes up with about a 5-minute outro.
