To go back to the government thing, the thing history teaches us is that humans are lousy at covering things up and keeping secrets. So while there are all sorts of examples of terrible things done by the people in government, there are those examples because the people couldn't keep it secret. Watch the current news and see how long the current administration has hidden its wrongdoing--what, forty-five minutes on average? Both Watergate and Iran-Contra were only about a couple of years from start to finish. Yes, the Tuskegee Syphilis Experiment went longer, but there are several things that explain that, not least the lack of interest. There is no corresponding lack of public interest in Apollo. Every aspect of the Apollo missions has been examined and reexamined by people from around the world. People, too, from countries with no friendship for the United States. And yet the evidence holds up. There are no deathbed confessions, no tell-all books, no whistleblowers. Just evidence. From a historical perspective, that alone means that the weight of evidence supports that the missions happened as described.
