I would like to know what is background story of all this? UFO stories have their hype each decade and I am interested why, is it some kind media diversion tactic or what? Because, I have feeling that no one cares anymore, at least I do not, after years of media "hypes" and "shocking" news my personal reaction to everything is meh. I have feeling that even if mother ship appeared one day I would have the same reaction. So, I am not sure what is there to hide. And how exactly would that change our perception about humanity. Religions will still exist, corrupt people will still exist, corporate greed, corruption, global warming and everything else will just continue as usual... Why anyone even thinks that some kind of external agent will save us from our selves and give us even more technology, when we are not capable of handling technology we have now?!
