Well written little book. Read it, thinking like a scientist and not a preacher, prosecutor, or politician.

Abstract from Amazon
Religion can be a very negative force in the world. This book shows how to use basic philosophy, historical evidence, and scientific knowledge to challenge religious belief in a non-confrontational way. It pinpoints the fundamental flaws of Biblical dogma, summarizes religion’s poor historical record and lack of trustworthiness, and briefly reviews the growing evidence that many Bible stories are based on natural phenomena. The state of scientific knowledge in fields including cosmology is shown to eliminate the need for supernatural explanations of anything. It explains how to guide Believers to a greater appreciation of skepticism and scientific methodology, and how the philosophical maxim of Occam’s Razor cuts through religious sophistry. It presents many common Believer fallacies, including misunderstandings of evolution, and provides the facts that refute them. It also presents the most incisive questions to ask Believers, based on simple facts and logic and proven effective.

Nor does the Bible prove God’s existence any more than comic books prove the existence of superheroes.

The bad news for Believers is that the current observational facts about the Big Bang argue against it being a supernatural phenomenon. It marks the beginning of time as we measure it, but there are theories, such as M-Theory, consistent with all observational data that say that the event itself could be just one of an eternal sequence of such events in a larger multiverse of universes (see the book The Hidden Reality by the physicist Brian Greene).
