The Book of Exodus tells of a miraculous parting of the Red Sea that allowed Moses and the Israelites to escape Egypt. Now, science has an older and more extreme tale to tell: About 6.2 million years ago, the Red Sea dried up completely.
Some millennia later, the dried seabed filled back up in a cataclysmic flood that may have carved a deep, nearly 200-mile-long (320 kilometers) submarine canyon into the Red Sea's floor.
