Atheist and Oxford professor Dr. Peter Atkins (a chemist) debates theist and also Oxford professor Dr. John Lennox (a mathematician and philosopher) on God, science, and atheism. Dr. Atkins gives an emotional, arrogant, and bigoted presentation, while Dr. Lennox responds rationally and analytically. Dr. Lennox has soundly defeated atheist Richard Dawkins in three debates, and was voted a winner against his debate with Christopher Hitchens. Now watch as he defeats Dr. Atkins!

I also recommend you watch Atkins debate with Dr. William Lane Craig: http://www.youtube.com/watch?v=hpPwfJO_DNE
