I think the biggest piece of evidence to support herobrine is right under our nose, they say that all mine shafts,wells and other structures were built by herobrine. But that isn't really my point. There is a disc that can only be obtained in a creative world, disc C418-11
if you listen to this disc you here foot steps and someone breathing heavily and im assuming trying to put something together. From the noises I hear i think it is somewhere in the nether. Herobrine is supposed to be a ghost right? And at the end of the disc you hear a monster yell and there is an abrupt ending. the disc animation is a broken disc so that cleary shows that something bad happened. Is this evidence of herobrine??
