Why does the sun shine?
The sun shines because the Sun Man makes the sun shine every morning and tells it to stop every night.
In the morning, the Sun Man tells the sun to rise. Then the sun does. The sun has to do what the Sun Man says because he is magic.
The Sun Man's real name is Supercalafragalisticexpalidocious. He lives on the moon with his wife, the fairy princess. She gave him the magic power.
Every morning the Sun Man wakes up, gets his magic wand, waves it in front of the sun and says "rise and shine." Then the sun has to rise and give us light.
The sun shines because the Sun Man makes it. Without the Sun Man, we wouldn't have light.
