I think that's how so many conspiracy theories spread. "IMO, I think it's very likely that the moon landings were faked. It doesn't matter since there is no evidence of the fake landings and any evidence of such will likely be covered up, like the way they got scientists to pretend that there are retroreflectors on the moon".
As long as people believe that evidence is covered up, then they can believe anything.
It's easier to believe in a grand conspiracy to make one seem special and part of a tribe than accept the banality, incompetence, chaos, and coincidences of reality.
