The moon fell from space and broke up as it entered earth, sending fire across the sky.
The children walking in the forest, found a chunk of it, not knowing what it was and seeing only a strange coloured ball, they played with it, throwing and kicking until the moon piece began to break up.
Each with a moon rock, the children decided to take their unusual find home, whilst unaware of the turmoil and terror that had befallen their world.
