After God had decided to cause a great flood to get rid of all the bad things on the earth, he caused a great flood, only because of Noah and his family, because they were the only people that was not doing bad, so instead of destroying the earth, he saved it by asking Noah to build the arc taking all types of animals and his family where they would be safe after the great flood.
