Why does everyone say that the undertaker died?
Well, To tell you the truth, the Undertaker actually did die, that's why he's called the "dead man", and if you ask how, a long time ago, some guy named Paul Bearer helped Undertaker's brother Kane burn the Undertaker and then he died and arose from the dead in that very same night, and that was around WrestleMania 13, which seemed like ages ago to some people, but that's exactly what happened.
