Maybe. But they actually look just as any ordinary person speaking in front of a crowd of people. Only professional politicians, actors, entertainers can do that and look "normal" at the same time. That is something that they learn for years. Its not the same in front of the camera and in front of the live crowd.
Yeah, the body language expert (Dr. G) didn’t eventually come to a definite conclusion about the astronauts’ behavior.
So it could just be that there was a tremendous amount of pressure and they didn't know how to act on TV that they didn't feel comfortable with it. It's also possible that there was lying and deception going on.
A few additional thoughts. He noted how in the comments under the video (he must have added an "epilogue" to it), people wrote that the three guys appeared to be sad and shameful. I guess the assumption was that that’s what they would feel like if the mission was faked and the footage was filmed in a studio. However, Dr. G said directly that there weren’t signs of those emotions, but rather of stress, anxiety and nervousness. I suppose this could be due to ”stage fright”, or them being stressed out for having to keep the truth about seeing aliens/altered realities (as the C’s implied) under a lid, or even a combination of both.
I'm not convinced that the lying and deception that may have gone on was specifically related to the idea that they didn't go on some sort of space mission that they didn't walk on the moon.
I recalled reading that Neil Armstrong left the public eye after the Apollo 11 mission and became a recluse.
There was a sense that he was reclusive. Perhaps the experience of the lunar mission had left him somehow traumatised, because life on Earth seemed an anticlimax after the heights of reaching the Moon.
Besides a possible ”traumatization”, there’s also a question of his personality: he was quite likely the most widely known man in the world at that time (the first man on the moon), and preferred a life out of the limelight.
The first man on the Moon would be remembered as the Charles Lindbergh of his generation, “a hero…beyond any soldier or politician or inventor”, and it was Armstrong’s lack of ego, his calmness under duress, his quietness, his confidence and his desire not to put himself in the spotlight of fame and attention made him the perfect choice.
