In the very beginning, the world had only light on one side and dark on the other. This is because the Sky Lady sat above the Earth with Her cape of midnight blue covered with stars over one half of the Earth. The other half was lit by a blazing ball. This ball was yarn that She was using to make a jacket for her son the Moon. The people on the dark side of the Earth only saw the Moon, but they knew his mother could give them light. They prayed to the Moon and asked him to intervene for them with his mother. He listened to their pleas and decided to try to talk to Her.
Now, the Sky Lady had expressly forbidden Her son to bother Her while She was creating his jacket. She was knitting and didn't want to drop any stitches because the ball of blazing light would burn Her fingers. The young and impulsive moon considered the ways he could approach Her. After thinking about all his options he decided that it best to sneak up behind Her. You see,being quite young, he did not always think things through clearly.
So, he crept up under the cover of his mother's cape of stars. As he was almost to Her, he stumbled and fell into Her. Startled, the Sky Lady jumped up which caused the blazing ball of yarn to fall from Her lap. Quickly She lunged for it, but it was just out of Her reach. She leapt to Her feet to chase after that ball, but it rolled along the horizon just ahead of Her. Her son knew that his mother was going to be cross with him so he thought it would be wisest for him to remain behind Her so he clung to her cape with a two fisted grip.
From the Earth's point of view,
we see the sun going across the sky and then the cape of night pulling
darkness, stars and the moon behind it. Really, it is the Sky Lady trying
to catch her ball of yarn.
