I gave a talk for Buckingham University Christian Union and their friends on July 31st.
You can listen to it below if you like (the video includes all the powerpoint slides).
It is a refined and substantially re-written version of a talk I gave a couple months ago. The latter half of the talk owes much to Tom Price of the Oxford Centre for Christian Apologetics.
