Alex O’Connor vs William Lane Craig: Does God Exist? The Ultimate God Debate

About this episode

A debate between Alex O’Connor and William Lane Craig on the existence of God, covering cosmology, suffering, and the Kalam cosmological argument.

Filmed before a packed live audience at London’s Royal Institution in May 2026, this Unbelievable? x Panpsycast x Theora co-production brings William Lane Craig face-to-face with Unbelievable? regular Alex O’Connor for a gripping conversation on God, cosmology and suffering. Craig makes the case for Christian theism, drawing on the Kalam cosmological argument, fine-tuning, moral values and the resurrection of Jesus. O’Connor pushes back on whether the universe really had a beginning, pressing Craig on infinity, time, causation and the Big Bang. The discussion then turns to one of atheism’s most powerful objections: animal suffering. Could a loving God allow millions of years of predation, pain and death?
