This debate is apparently is from October 2007, but it was posted recently on reddit, and I thought I would repost it here. I found this written about it:
In Birmingham, Alabama, Professor Richard Dawkins and his Oxford University colleagueProfessor John Lennox engaged in a lively debate over what is arguably the most critical question of our time: the existence of God. The debate centered on Dawkins’ views as expressed in his best-seller, The God Delusion, and their validity over and against the Christian faith. Both presenters agreed to the format and topics of discussion.
