Recently, George Williamson debated William Lane Craig and Michael Horner in Regina and Saskatoon on the topic: Does God Exist? I haven't watched or listened to these debates yet, though I have listened to Craig's first debate with Williamson (it was OK). Given my impression of their first debate, I'm not all that interested in listening, but I'm sure I will soon. Williamson has wrote a review of both of his debates with Craig and Horner that can be read by clicking here.
His review is an interesting read mostly because he actually admits that his first two arguments are weak! Of course he didn't admit that in his debates. Williamson says that his giving the first two arguments (though admittedly weak) could lead to a more extensive case that everything we know in the universe points to the absence of a god.
This is a good read. You can check it out by clicking on the following link below.
