It’s not a “so-called conspiracy” it is a conspiracy theory.

Thousands of people worked on the Apollo project. Hundreds of America’s best engineers spent a decade designing and improving the designs for equipment that would go to the moon. If it was really impossible to do it in the 60s, you don’t think some of those people would have come forward by now? And not Bert Sybrils version of “my buddy’s uncle’s friend left his son a confession tape that was destroyed in a fire” version of coming forward. I mean someone from Boeing, or Northrop, or Rocketdyne, or even JPL itself would have said something. You’re talking about keeping thousands of very smart people quiet about something that would have been obvious to them from the start, and asking them to waste a decade of their life designing things that wouldn’t work.

Apollo missions after 11 left scientific instruments on the moon like laser reflectors that let us calculate the moon’s distance from earth more accurately over time. Non-US agencies and universities have used these for lunar observations. Are independent agencies lying for the American government, or are there really reflectors on the moon. If they’re lying, why? What benefit would they gain? If there are reflectors on the moon, how did they get there?

The US government spends millions of dollars every year meticulously preserving lunar rock samples. If it was fake, why would they continue spending that money 50 years later? Why not say “all rocks gone, everyone is fired, go home” 40 years ago? For that matter, those rocks have been sent to thousands of research centers, universities, and labs around the world for analysis and testing. They’re the rarest and most valuable rocks in the world. If NASA shipped some random rock from the Arizona desert to a lab in France or Germany, don’t you think some French or German geologist would go “hold on a minute, this is just ordinary basalt!” And call their local newspaper about how nasa just scammed them and wasted their grant money?

24 astronauts have orbited the moon, and 12 of them walked on it. These are men who dedicated their lives to being the best at what they do, a good chunk of them had doctorates. Again, you’re saying that 2 dozen people wasted a decade of their life training to be the best of the best so they could go to the moon, and then just what, sat in a bunker for a week and then said they went to the moon? And not a single one of those 24 men ever said it was all bullshit? Clearly you don’t understand American history or culture if you think that’s true. We like the big slamdunk, knock out drag out, victory. If that wasn’t true, someone would have blabbed about how they wasted their life for a fake crowning achievement.

Just because you don’t understand how something works doesn’t mean it’s impossible. Go play kerbal space program or read a book on project Apollo if you want to actually understand how space travel works. Watching YouTube videos is not going to educate you.

That is not what is happening here. The problem is that your moon landing conspiracy is incredibly stupid if you really think about it. It would require mass cooperation in subterfuge on a scale that would require a lot more resources than actually landing on the moon.

Edit: The moon landing can also be proven today by third party methods.
