In case you don't it, these are the explanations:
- The comment by Rocckir just states that the video is obviously fake, with no evidence or explanation.
- The comment by BigMike133 confuses the Space Shuttle (which was never capable of landing on the Moon) with the Apollo Lunar Module.
- The comment from GunPistolMan claims that the video is fake due to the mistaken belief that the Moon would have no gravity, whereas in reality, every object in the universe that has mass has gravity, including the Moon, comets, asteroids, moons of other planets, even yourself, and so on. The gravity of the Moon is approximately 1/6 the gravity of Earth.
- The comment by CrackMonkey74 names Louis Armstrong, a famous jazz musician, who may have waxed lyrical about the moon, but never went there. The ill-informed commenter actually means Neil Armstrong, who was the first person to walk on the Moon. The dare to accuse Armstrong to his face may be a reference to an incident where moon-hoax conspiracy theorist Bart Sibrel confronted Buzz Aldrin and called him "a coward, and a liar, and a thief." Aldrin responded by punching Sibrel; Sibrel's attempt to bring charges was dismissed on the grounds that he had provoked Aldrin to the point where the punch was a justified response.
- The user SimplePlan2009 is likely mocking the other commenters. While the conspiracy theorists frequently claim the Apollo footage was shot on a "soundstage", the poster takes the ludicrous position that the Moon shot was faked by actors filming the scene on Mars, a planet that at its closest approach to Earth is over a hundred times farther away than the Moon. Landing humans on Mars (much less landing enough people and equipment to set up a soundstage) is a feat that has still not been accomplished, and if it had been possible during the Apollo era, the landing on the Moon would have been a trivial task in comparison. In other words, why go through all the trouble of faking it, if doing it for real would have been no trouble at all?
