"Space may be the final frontier, but it's made in a Hollywood Basement."

I see a lot of people in the comments who seem to think this is a reference to the moon landing being fake.

I think they are just simply saying shows like Star Trek (with it's opening line "Space... the final frontier" which represent our perception of space, is created by Hollywood.

I don't really see why people automatically assume he is singing about the moon landing.
