Anyone can be right when they're guessing. NASA never denied there was water on the moon, they just couldn't prove it. I always thought there must be water ice in the shadows too, so I guess that makes me right as well, even though it was just a guess. The conspiracy boys didn't know anything anyone else couldn't have known. As I said, there was no conspiracy here. In fact, I can go further by saying I believe some day we will find a way to travel to other stars, either by FTL or by generation ships. That's a yes or no type of question, so I have a 50/50 chance of being right about it
And as for an atmosphere on the moon, lol, it's almost nothing. In fact, there is likely more atmospheric pressure in some gas clouds than there is on the moon. The moon is as close as you can get to vacuum without actually being open space.
