The Deluge



The Deluge was a global flood that occurred on Earth early in Human history.

This event was mentioned in the Bible; in the Book of Genesis, which mentioned how Noah and his family were spared from death by God, who instructed them to construct and ark for them to take shelter in.

Some believed that this event and the Great Cataclysm were one and the same, although the latter only involved the sinking of Atlantis, not the entire world being covered with water.

When the Parademons were attacking Earth, Green Arrow said that if that's a minor catastrophe, "Noah rode out on a light rain!"
