LOL, I just found this after finding the blue planet object on Google Sky. I just switched over and 5 min later found this on the moon. The dark black square is 70 meters by 70 meters according to google ruler. However this is also some thick framing around it which causes me to think this is an entrance and exit point for small craft to reach inside the moon. You see, the moon is hollow, an Apollo mission which measured the echo of a lander rocket recorded that the moon is hollow. So with that point made, this 70 meter dark square with the think frame does appear to be an open doorway. This is 100% proof that intelligent life exists below the surface of the moon.
