Several cultures in the ancient Mediterranean have some version of the Flood story, which tells us that whatever form this traumatic event took, it left a lasting cultural memory across the Western World. Unlike other Flood narratives, the Bible makes it clear God is in charge. God is fully in control when the waters are loosed and when they are bottled up again. Not only that, we are safe from any world-wide cataclysm, because God has made a covenant with us. The rainbow is a sign that whatever we might do to each other, God will not destroy life upon the earth again.
