We all know "Herobrine" as a mob who kills you, taunts you, or scares you. But do we all know of how Herobrine was created? The story is a little something like this... Herobrine is not in minecraft, nor was he ever. Encounters on websites are just haux's. They might have had mods without they're knowings. Notch puts on every update that Herobrine was removed. He does that so players will not spam his email or MC forums that he was in they're world. The reason he does not exist is because in minecraft, there are no coding systems to spawn redstone torches, yet. Nor are there any codes to spawn a mob like Herobrine, Since he moves and talks and fights like a player, it is impossible to get a mob like him to be in vanilla minecraft without mods. What is Herobrine? The answer is Herobrine is Notch's dead brother, though Notch doesnt have a brother, so its not possible. Another answer is, he is a ghost miner, that was killed when he was mining in an abandoned mineshaft, thus the reason its abandoned. Herobrine is a myth, and never has been in Minecraft. Do you think im lying because he is in Xbox? After Herobrine was made up, Notch thought it was a neet idea, and added him to Xbox. Though he does not place redstone torches or do anything people think he does, he just wanders around. Explanations show that he could be an imagionation, for the player has read about Herobrine, and now THINKS he is in the players Minecraft worlds, but he is simply an imagionation of the players myth-filled mind.
