They didn’t. They did confirm ufo sightings but there’s nothing said on aliens/extraterrestrial origin.
Grusch has sworn under oath that there are departments in the government that have actual alien crafts and bodies.
I welcome physical proof as well. But this isn’t Bigfoot or Loch Ness or anything like that. There’s a mountain of testimony spanning decades. Too much smoke for there to be no fire.
Every time I hear the phrase “under oath” I mentally replace it with “pinky promise” because it all has tbe exact same amount of weight. There’s no reason to assume someone is being truthful just because they promised you they aren’t lying.
Then there is the technicality of “if they believe it is the truth then they aren’t lying” so as long as other have convinced them enough for them to believe it, then they haven’t broken their oath.
This is just meaningless elementary school behavior from adults and anyone that can’t see that or thinks oaths and such symbolic social constructs are meaningful are not worth taking seriously.
Unlike pinky promising, there are serious criminal penalties for lying under oath. It’s perjury and counts as a felony and comes with up to 7 years in prison. Not to mention what it would do to your career, especially a career in the military/intelligence.
