May 21st Doomsday

Who knows about a day which some people though that is the end of the world. They just give opinion that May 21st Doomsday is end of this world. That'd happened? I don't think so about that, guess what, we still live until now, nothing happen with this world. What people think about May 21st is just imagination. What kind opinion can make decision that May 21st as Doomsday? run off solar ray? may be it can be some reason, but there are still some reason.
