That is very true but this topic is completely outside of science so the best way to find out if it is real or not is to do it yourself. There are actually CIA documents on this and it is very thought provoking, I linked the post at the end of my first comment. It's actually a tragedy just how many ignorant people there are on the planet that automatically dismiss anything that is hard to believe instead of investigating it. I am not trying to convince anyone to believe me at all, I am simply just presenting an interesting topic that might interest people because this stuff is very otherworldly but that doesn't mean it's automatically fake. There is no proof that it is real, but there is also no proof that it is fake so you cannot deny the possibility of it actually being real.
