Question of authority has been part of the human mind since the dawn of time, yet most of us tend to trust our government, but many don't. People say that the government is hiding this, medical experiments, aliens (of which I am an advocate), but a common theory is that NASA faked the moon landing footage, some say it was directed by Stanley Kubrick. While I do not believe in such things, I've teased the idea. If they did film it with actors on a set, it's a very convincing production.
Buy a driving point on this theory is, why have we not gone back? Some people say that there is nothing left on the moon to discover, some say it's because the whole thing was a hoax. Either way, we haven't gone back
Well, maybe we had a Damn good reason
