I agree that you would have to be one arrogant SOB to believe we are the superior race in 1 little galaxy out of many that look like this
I also believe that you would have to be pretty damn stupid to believe that our current most advanced flight technological capabilities rest at a B2 bomber designed over 30 years ago and a U2 spy plane designed around 60 years ago.
Fact is Hitler was trying to develop "UFO's" during his time and all of his top scientists were were extracted out and spread around the World but mostly brought to the US to continue on. In addition to trying to develop UFO's he was also faking UFO invasions to scare people.
