What makes me believe it the most is the fact that the moon landing was a race between several countries, biggest countries at the time and somehow conspirators think the USA was able to fake it in such a way that they fooled entire nations to believe them? And somehow now years later some youtube idiots were able to find out? Seems quite improbable.
Very true. The race then was between Russia and the USA. I believe Kennedy was the president back then, when the Russians sent Yuri Garin to space. In Kennedy's desire to show the world that America wasn't lagging behind either , I believe that's how the conspiracy theory came about. Because nobody had envisaged a moon landing so early in the race.
