I forget where the passage was exactly, I believe Matthew or Revelation but the chapter was talking about false prophets and prophecy. It talked about determining the difference between a false prophet and a real one. It said that if they are wrong once, throw them away. A real prophet of God will never be wrong. Your little Myan calanders for instance, sure its predicted roughly some things here and there, and its also been wrong. Therefore its a load of BS, same goes with all these other bigshots claiming when the world is going to end.
