The film presents the latest archaeological scholarship from the Holy Land to explore the beginnings of modern religion and the origins of the Hebrew Bible, also known as the Old Testament. This archaeological detective story tackles some of the biggest questions in biblical studies: Where did the ancient Israelites come from? Who wrote the Bible, when, and why? How did the worship of one God—the foundation of modern Judaism, Christianity, and Islam—emerge?

The producers surveyed the evidence and take positions that are mainstream among archaeologists and historians, although they continue to raise objections among both Christians who believe in the bible as either literal or historical truth and minimalists who assert that the Bible has no historical validation.
