The story of Noah’s Ark can be found in the Book of Genesis in the Hebrew Bible (the Old Testament in the Christian Bible). God became angry with the world and its sinful people, and sent a flood to destroy it. He ordered the good man Noah to build a giant wooden ark to save his family, and to bring two of every kind of animal onboard. When the flood waters receded after forty days and forty nights, Noah and his family, and all the animals, were able to re-populate the world.
