Armstrong and Aldrin both say they were being observed during that mission, inside the crater they were in. Multipal large alien craft was seen on the edge of the crater-observing the astronaut's activity. I'm convinced of the truthfulness of the two men. The existence of an extraterrestrial race is qute possible and is being kept from the public. The excuse from those inside says the public couldn't handle this information. Note: because of the speed of this video, you need to pause it to read all the information presented. There are other longer videos on Youtube on the subject if you want to look at them
