"The World on the Turtle's Back" is an Iroquois myth that explains how the Earth was created. It is like the Christian myth where God creates the world in 7 days because both are based on people's beliefs and try to explain how everything was made. As in many other myths, the Iroquois one has many examples of balance and complementary opposites. For example, in this excerpt you can see: day-night, left-right, light-dark, etc. So, it's necessary that both twins exist at the same time, they cannot die because they are immortals and are always present.
