"Does God exist? Using an intellectually rigorous, scientific approach, Marshall Brain (the founder of HowStuffWorks.com and author of the How Stuff Works series) sets out to resolve the eternal debate once and for all. With a compelling sense of curiosity, he breaks down mankind's search for a higher power, tackling such quandaries as: Who is God? What are his attributes? What is God doing and why? How does God interact with humanity? And ultimately, how can humans know with certainty whether God is real or imaginary? How God Works is an enlightening journey in critical thinking that challenges readers to boldly approach the subject of personal faith and put aside intuition in favor of objectivity and logic."--Publisher's description.
