An even more unassailable bit of evidence, for me, is that Russia never claimed it was a fake, despite having the obvious capacity to verify (just by training their best telescopes on the landing site, and probably a dozen other ways) and the obvious benefit to them if they could show America had faked it.

No conspiracy short of a One World Government could have pulled off a fake moon landing— and if a conspiracy were powerful enough to orchestrate a fake Cold War, one wonders why they would have even bothered with PR stunts.
