In the face of increasing attacks on Christianity by militant new atheists, Christians should be able to robustly defend their beliefs in the language spoken by Christianity’s detractors—science. Atheists claim that science and religion are incompatible and in constant conflict, but this book argues that this is assuredly not true. In order to rebut the polemic agenda of the new atheists who want God banned from the public square, this book engages with the physical and natural sciences, social science, philosophy, and history. It shows that evidence from these diverse disciplines constitutes clear signposts to God and the benefits of Christianity for societies, families, and individuals. Answering the New Atheists begins by examining what new atheism is, before demolishing its claim that Christianity is harmful by showing the many benefits it has for freedom and democracy, morality, longevity, and physical and mental health. Many historians of science contend that science was given its impetus by the Christian principle that a rational God wants us to discover his fingerprints on nature. Thus, in subsequent chapters, Walsh presents a well-informed and philosophical-based analysis of the Big Bang and cosmic fine-tuning, the unimaginable improbability of factors that make this planet habitable, and the multiverse often called the “last refuge of the desperate atheist.” Interdisciplinary in its approach, this book adeptly explores the very problematic issues of the origin and evolution of life that have forced many top-rate scientists including Nobel Prize winners, who have thought deeply about the philosophical meaning of their work, to accept God as the Creator of everything.
