Who created the Universe? Is a creator even necessary? Can science explain how the Universe came into being without reference to a creator God? This booklet explores these ideas and the arguments that have been brought into sharp focus by Stephen Hawking’s claim that his cosmological model ‘left nothing for a creator to do’. Dr Carroll examines the Church’s teaching on creation from Augustine and Aquinas to the present and explains why, without a creator God, science itself would not exist.
