A couple of weeks ago Christian philosopher William Lane Craig debated naturalist cosmologist Sean Carroll on the question whether theism or atheism is the best explanation for the existence and nature of our universe. It was a fascinating exchange, sometimes a bit too technical, but often accessible enough to laypersons to make it edifying.
If you're not inclined to watch the whole thing I recommend Craig's initial presentation of the kalam cosmological and the teleological arguments. His presentation is succinct and lucid.
Craig usually makes short work of his debate opponents but Carroll was much more formidable than anyone I've seen Craig debate in the past. Even so, I don't think Carroll, for all his brilliance and eloquence, really came to grips with Craig's arguments, but others will certainly have a different take on it.
