And this is exactly the way it always is proported (by conspiracy theorists) to be. They alone have stumbled upon the world's greatest secret!! Aliens have visited them, God has talked to them, the ancient summarians predicted it...whatever it may be. One person starts a ruckus, and then people jump on board.
I tend to think it is something psychological for these people who believe in this sort of thing; perhaps that they WANT to believe in something more than just the ordinary. I even find myself very interested in reading what they have to say, it has some strange attaction. Mind you, my common sense is alive and quite active, but I often find myself fascinated with the unknown and unexplained. Some people are obviously so fascinated they are able to block out common sense in order to believe what they want to believe. Suppossedly, planet X is going to slam into earth sometime this spring. Common sense woudl tell you any amateur with a half-way decent telescope would be able to see the planet by now, especially since its supposed to be a lot larger than earth. But I'm sure they have some explanation as to why this is not possible. What they want to believe dictates the way they think. Those of us who still have a shred of sense left can't understand how someone could be so blind.
Of course, maybe thats just what the government wants you to believe
