Please write a story about the sun and the moon joining forces to fight aliens. The sun and the moon both have special rays that can defeat the aliens. In the end, make sure the aliens, the sun, and the moon are friends. The year is 4000 and Earth has an open line of communication with the Sun. The story should be ten to fifteen sentences.

It was the year 4000, and a fleet of unmarked spacecraft appeared way out in the depths of space. As the mayor looked up and saw the spacecraft, he thought to himself, "Oh my goodness, it's aliens, and they're coming to attack us!" The mayor quickly got on the phone and called the Sun. "Hey, Sun, please help us!" the mayor shouted. As the Sun turned around, it saw the aliens on their way to Earth. The Sun, knowing he was outmanned, shot a fireball at the moon to get its attention. The moon whipped around to see the spacecraft's hurdling toward Earth. The Sun looked at the moon, and the moon looked back at the sun. They nodded at each other and began powering up their special rays. After about five seconds, the sun and the moon unleashed their rays directly at each other, causing the two rays to combine and create an impenetrable forcefield that the aliens could not get around. The aliens, seeing the forcefield created by the sun and moon, immediately stopped their spacecraft. They flew a white flag on the lead spacecraft and flew up to the Sun to talk. As they spoke, they realized they had a lot in common. The aliens weren't there to attack Earth; they had just gotten tickets to see the Yankees and Red Sox play. They all had a good laugh and became good friends.
