I think there is some compelling evidence that NASA is not truthful about space exploration. The main problem is the real questions get diluted with ridiculous notions of a flat earth and it makes people associate those who believe the moon landings were faked and much of space exploration, with those who believe the earth is flat. Once people start connecting those two groups, they all are immediately dismissed and their arguments rejected without consideration. You see the same tactic with 9/11, the no plane theory gets thrown into every argument so everyone immediately dismisses the other evidence of controlled demolition.
The most interesting things about the moon landings IMO:
All video of the moon landing was filmed directly off the large NASA screen at mission control. Nobody was allowed access to the direct feed.
NASA claim to have "lost" all of the original film footage of the moon landing, so now all the footage that is available is what was filmed off that screen.
Nasa claim to have "lost" all the technical data and technology that allowed them to travel to the moon, which is why they are not able to go to the moon again in the forseeable future.
