I don't even try to argue people about this anymore. We have third party evidence, where universities and institutes tracked Apollo (11 - 17). We have the lunar orbiter sending back images of the landing sites. AND we have reflector mirrors set up by astronauts on the moon that we can shine lasers at, receive the laser reflection, and calculate the distance of the moon to the earth. This way we can track how fast the moon is moving away from the earth on a yearly basis.
Don't you think the USSR would have called America out on the moon landing as soon as Apollo 11 happened? Or would have sent their guys to "prove" that Apollo never made it to the moon? These conspiracy theories never add up and the only reason they work on some people is because they confuse the gullible.
The spacecrafts walls (slightly more thickness than a tin can) and space suits could not have protected them against the solar radiation or the extreme temperatures (-250 to +250F).
The position of the lunar lander on the moon changes during the same mission.
The same mountain backdrop is observed during different Apollo missions and landing sites.
No sound of an engine heard over Armstong's headset mic when the Eagle is getting ready to land.
No moon dust disturbed at all when you look under the engine of the lander... there should be dust all over the foot pads of the lander, but they are totally clean.
The pictures of the astronauts and objects are casting diverging shadows... that doesn't happen with one light source that is very far away (sun).
Critical observation/thinking leads me to believe the whole thing was bogus.
