So far we’ve seen strong indications of the authenticity of the crewed Moon landings, which are quite convincing for anyone who considers the balance of evidence. They show that any attempt at fakery would have been absurdly complicated, but they aren’t proof, strictly speaking. Certainly they’re not definitive proof for a hardcore Moon hoax believer.
If we’re looking for proof, what we need is something that demonstrates beyond doubt that in 1969 there were no bizarre robots in boots hopping around on the Moon, but that human beings were actually there. Something that documents an event that could have occurred only on the Moon half a century ago and in the presence of astronauts. Something preferably provided by an independent source, not by NASA.
Surprisingly enough, such proof exists.
