Hitchens trys to run from the question but Craig goes in for the kill and finally pins Hitchens down when Hitchens says he is atheist and God can't exist. In that moment Hitchens made a truth claim and now has to back it up. This is where Craig takes control of the debate and Hitchens hits the mat for the knock out punch. Atheists were very upset at Hitchens failure to bring arguments to this debate. It seems like Craig was prepared for the debate but Hitchens spent most of his time talking bad about Islam and other things which wasn't even the topic of the debate. Craig wins this one.
UPDATE: After this debate Richard Dawkins began to cower from any 1 vs 1 debate with Craig. Even Sam Harris has stated that and we quote him "Dr. Craig has put the fear of God into some of my atheist colleagues".
