This week on Flightless Bird, David sets out to understand religion in America. Joined by Dax and Monica, he tries to figure out why over 200 million Americans are Christians, and how uniquely Americanised this religion has become - with franchises, brands, and celebrity endorsements. David talks to Mike McHargue - a Baptist who became an atheist who then became a Christian again. We discover how someone can love both Christianity and science - and you may be very surprised to learn your brain may well believe in God… even if you’re a stone-cold atheist!
