Because they are a real thing. And its becoming clear that the government has been “studying” them for decades. The days of ridiculing people who report them are over.
Bob Lazar worked at Los Alamos. He then worked at area 52 (beyond Groom Lake) studying the gravity altering system in a “craft” that he was not sure of the origin.
Lazar stated he was ONLY allowed to work on this one system of the craft. He worked with one other person. Other two person teams studied other systems.
By altering the gravitational field around the craft it could fly at much higher speeds than anything the USA could produce.
It also had the ability to change direction dramatically almost instantaneously.
