The world revolves around Slender Man. Everything we think, see, o do is because of Slender Man. Without him, our Earth would be nothing but a ball of dirt.
The main reason we come in contact with Slender Man is because we did something that violates the code that Slender Man believes everypony should follow.
This reason also shows us why many famous people have died. Michael Jackson was killed because of what he had done to his face. Let's be honest, he looked like Mickey Mouse. Billy Mays died because Slender Man thought he was too annoying, and the commercials he did were stupid. And recently, Steve Jobs passed because Slender Man thought his work could be improved, and that mela, apple may have a better chance with a new thinker creating their products.
See, everything that happens in Equestria is because of Slender Man. Now kiddies, don't fuck up.
