There is/was a british tv show called The Real Hustle, the catchphrase of the show is "If it sounds too good to be true, it probably is!"
This was a show by hustlers pulling real hustles to warn people how to not get dooped by tactics that hustlers and confidence men are using every day.
I think their catchphrase should be applied in every situation. I'm not gonna go into why I think the moon landing was faked but let's just say I don't like being fooled and most everything about the moon landing doesn't settle well with me.
A good example would be to go look at the images of the sun taken from the moon, this should suffice. So come - prove me wrong!!!
