Not taking sides in all this, but...  I have always thought/suspected that there were Satanists, Cannibals and pedo's.  I have always suspected that there is a NWO/Illuminati out there trying to take over the world.  The one thing that would truly rattle me would be an intergalactic war being waged on Earth.  The problem with the above story to me (aside from lack of proof) is an intergalactic race would not need us to kill ourselves.  They can travel the galaxy but cannot make a plague or toxin or a murderous group of nano bots or something?  ESPECIALLY if they arrived before we had nukes, gun powder, electricity, internal combustion engines etc.  Anyway; just my opinion.
