You have to be careful of info that is leaked, not leaked....................or maybe a U-man camping outside the base saw the stealth fighter as it flew across the sky and the supersonic boom scattered his orange booty leotards freshly laundered in a mud puddle across the open field. Sometimes the leaked info is planted to cause concern from their opponents. Does Area 54 really contain captured aliens or is it where the military develops their next generation military aircraft. Other life forms do exist on other planets, but they are too far away to get here and too far away for us to get there. Just going to Mars you will have to developed the technology for the one way trip and then spend two years drinking a shared pool of distilled piss and eating dehydrated meat and vegetable crackers. Only to crash and die on a far away planet.
Military secrets are over or under exaggerated to keep the information secret.
