The narrative about the flood is: at first, a creator created the world. Later, human betrayal, pain and death entered the world, which became more and more fierce. So the creator destroyed the world with the flood, and only eight people were saved. Their descendants all inherited the story of the flood from them. But later, a man named nimrod organized people to revolt again and built the Tower of Babel. The creator organized this activity to spread mankind around the world. Therefore, human beings still retain the memory of the great flood, but gradually, people in different places forget or supplement some details, resulting in different versions.
