Bill was born to Albert Einstein in a year Albert Einstein was alive. Nobody knew that Albert had a son named Bill. In fact, Albert had Bill's last name changed to Gates so it would be kept a secret. Also, Nobody knows why he did this.
Bill grew up on Earth, and raised in the ways of the humans, as he was one. There is only one tradition of humans he refused to follow: DINNER (which is why someone once gave him pie (à la Anita Bryant)). Bill,unlike his father, was very dumb.
Bill Gates created a company known as Microsoft (in fact, a lot of people did, but he took all of the credit). He now runs this company, and is the richest company ever (except for companies).
His wife then gave birth to Mark "Gates" Zuckerberg in 1984, and Bill raised him until Mark became a very rich guy and owned a huge company like his father.
But then one day he started to sell juice and he killed 2000 people with it. He joined a wierd guy to eat lotsa spagehtti.
