the sun and the moon

There were a set of twins named Sulphur and Mercury. They were always fighting with each other. Sulphur liked to eat fire and Mercury liked to eat stone. They ate until at last, there was no more fire and stone left to eat. One day, a wise man came to visit and asked them, " Do you want to eat more fire and stone?"
"Then i have the best job for both of you". "Sulphur, your job is to eat all the stars in space and Mercury, your job is to eat all the asteroids in space". They followed the wise man and rode on a weird creature into space. The wise man left Sulphur in the east and Mercury in the west. They ate and there was still more to eat. They grew big and round like giant balloons that until today, you can still see them floating in space. With all the fire in him, Sulphur had turned into the sun - hot and red. And with all the stone in her, Mercury had turned into the moon - cold and white. And they never fought with each other again.
