If you don't know who Bob Lazar is, search on YouTube, he's all over the place talking about when he worked at area 51 ( S4 subsection, actually ) where he was assigned to reverse engineer a UFO, one of nine the gov had in their possession ) This Body Language expert takes the task of evaluating Lazar's body language to see if he is lying, because, well, he explains it, and he's very convincing.
I believe what Lazar said. The government has been covering up the truth about UFO as furiously as it covers up the truth about Covid.
