"UFO's" have NOTHING to do with aliens! Flying saucers and other advanced spacecraft are probably made by Boeing and Lockheed Martin.

If you want to seriously discuss any this, the very FIRST step is dissociating "aliens" from "flying saucers" inside your mind. Make the effort! That bogus association has to do with repetitive and extensive propaganda and obfuscation in the U.S. media and Hollywood since the 50's. So, at the end of WW2 they were made by German scientists, a few years later they were made by ... aliens?

 It's unbelievable how people still fall for this crap after being aware of nukes, HAARP, petrodollar, NSA scandals, hidden or stalled scientific knowledge and other critical topics
