Legendary British philosopher and atheist Antony Flew turned from atheism at the age of 81. A noted critic of God's existence for several decades, Flew published books like God and Philosophy and The Presumption of Atheism.

Dr. Gary Habermas, prolific philosopher and historian from Liberty University, has debated Professor Flew several times, and they have maintained a friendship despite many years of disagreement over the existence of God.

Habermas interviewed Flew in 2004. A piece of their discussion follows:

Habermas: Which arguments for God's existence did you find most persuasive?

Flew: I think that the most impressive arguments for God's existence are those that are supported by recent scientific discoveries…. I think the argument to Intelligent Design is enormously stronger than when I first met it.
