 Liddle focuses on objections to evolution halfway through the documentary, on the premise that "Darwinism is atheism's trump card".He characterises the creation–evolution controversy as being between scientists "who see no room for religion in the world" and ones "who can accommodate both a scientific and religious worldview".Liddle interviews the intelligent design supporter Steve Fuller, a philosopher, who argues that evolution is the only "scientifically credible basis" for atheism, and anthropologist Jeffrey H. Schwartz, who argues that evolutionary theory cannot account for novelties.
