It's my go-to counterpoint to moon landing conspiracy theorists because there is no reasonable argument against it. The physical evidence and data itself is undeniable, but it is hard to explain succinctly. The fact that the Soviets didn't try to deny the US landing though, there's no real explanation for that other than "it actually happened".

Did we really land on the moon?

this is the main argument against a moon landing conspiracy and it certainly is compelling that both them and the chinese would know  it was fake just via satellite reconnaissance alone
