When people invent elaborate mythologies and fictions like the Apollo moon landing hoax conspiracy theory, it’s important to remember, that it’s never about the theory, it’s about the theorist. Conspiracy theorists latch onto a few perceived anomalies as the basis of their theory and ignore the mass of contradictory evidence. They also tend to ignore any reasoned rebuttals of their ideas, and any information that would tend to contradict what they are presenting, no matter how convincing. They are always willing to replace the obvious with the preposterous, because it’s really not the theory that’s important, but the idea that they have special knowledge that the rest of the public does not have, and that they have uncovered a secret that most of the rest of society is too blind, brainwashed or stupid to see. These things are very important and dear to our conspiracy theorist. They will look past reams of evidence and testimony to find that one little bit, the hair on the negative, lens flare in the photo, the misspoken word, the missing document, and conflate this into a massive myth that literally requires the collusion of thousands of people to seemingly be possible. This is how the legend of the Apollo moon landing hoax was born, when one disgruntled ex-technical librarian with an axe to grind made up a story about faking a moon landing. People being who they are, some believed it, since they have a need to believe in secrets and conspiracies, even though the information in that book was quickly debunked and shown to be nonsense. But it survives to this day, providing more fuel to the people who feed off conspiracies as a way to feel special and superior. Since the Apollo missions are now some 45 years in the past and we have several generations who didn’t witness them or understand their context, they continue to find a ready audience for their nonsense. All the sensible people can do is continue to point out the truth as history has recorded it?
The Apollo program and lunar landings were undertaken with the expectation that other countries, particularly the Soviet Union, would also be landing on the moon within a few years or perhaps even months of the NASA effort. Faking the Apollo missions would have been a seriously risky proposition, based on the fact that not only might another country choose to land near an Apollo site, but eventually others would explore or colonize the moon and find out that the missions had been faked. Therefore, regardless of the many debunked claims made about inadequate technology or deadly radiation, or other such nonsense, there was no real incentive, ever, to “fake” anything about Apollo, given the whole thing was under world scrutiny. What would NASA have done if they had faked it, and then 5 or 10 years later somebody else had landed there and found out the whole thing was a hoax? It would have precipitated a major political crisis, obviously. So given that, it’s pretty clear, aside from the mountains of evidence and data freely available to anyone, that the Apollo program was genuine and the landings happened as recorded, that “faking it” would have been completely unacceptable, even assuming there had been any motivation to do so, which there was not. The many thousands of engineers and scientists who developed and worked on the Apollo program were honest people with scientific integrity. No one has ever seriously called that into question, nor has anyone ever come forward with the slightest evidence of dishonesty or deception. People making these claims do so only out of their own personal delusions and vendettas, and lack both knowledge and credibility.
