Millions of years ago, when the world was first formed evaluation created purple aliens, green aliens and humans. The main food source was the insects that roamed the Earth.
Eventually, due to the humans ignorance the insects became extinct. This made the aliens very mad at the humans for eating all of there food. Out of anger they made the humans there new food source.
After the humans became the aliens food source, there wasnt many left. The aliens started to fight over the last of the humans. When all the humans were eaten or killed the purple aliens and green aliens went to war. Eventually all aliens survived but one.
His name was Fernando. He was very lonely and hungry. Everyday he looks for something to eat. Until one day he went into a cave and found a magic slime. When he ate the slime it gave him magic powers to fly through space infinitely.
Ever since hes been flying around all the planets looking for insects, animals, humans or anything he can eat. There was a God who controlled earth's weather. His name was Erditheus.
Fernando has been flying for thousands of years before evalution started up again and made humans. Within a few centuries humans were covering the Earth again, But fernando was still looking for food. Erditheus knew that if Fernando saw the humans when he flew by he would eat them. So whenever he was about to fly over Earth in search of food Erditheus made clouds cover the earth. When he covered the earth the humans were unseen. And this is why we have cloudy days.
