*puts tinfoil hat on*
The Moon really is made of cheese, but NASA staged the entire "Moon landing" thing to fool people into thinking that wasn't the case, and that it was just a pile of inedible rocks.

You see, if people had proof that the Moon really was made of cheese, they would have an infinite food resource and Big Farming could potentially go bankrupt if they couldn't fool people into buying food, instead of just eating free Moon cheese.

*takes tinfoil hat off*
I'm kinda hungry right now. I should eat something. I'm in the mood for some cheese.
