This video clip shows excellent footage and explanations of lunar bases which were found on the moon. According to the dialog and movie, there is no doubt that alien bases exist on the moon, and NASA has known about them for decades.
The video describes the bases and confirms the notion that NASA Airbrushes photos before they are released to the public. This video is quite interesting, and can be found on Google Videos. The video is rather large (12 Mb).
