Overview: It's one of the greatest and strangest stories ever told, the biblical tale of God unleashing 10 plagues on Egypt until its pharaoh released his Hebrew slaves. Scholars have categorized this as a parable, but now, new evidence found in the ruins of an ancient Egyptian temple suggests that an apocalyptic natural disaster rocked the world 3,500 years ago and may be the true cause of the ten plagues. If the experts are right, our understanding of the Bible, and 3,500 years of Egyptian history, will change forever.
