Here on earth, the moon is this big white thing that lights the world and hangs in the sky. Every culture on the Earth has incorporated the moon into some of their legends. Sometimes as a woman, sometimes as a man, sometimes as a major god, sometimes as a lesser god. However, on an forested moon of Earth-like description, circling a blue and green super Earth of 3x the size, the stories would be different for no other reason than because they have no big white ball in the sky.
Clearly the stories they tell their children will be radically different than the ones we tell our children. Specifically, how might their creation myths be different from Earth's with their giant blue-green super Earth as their "moon"?
