"Ever since their first day of landing on the Moon, the Germans started boring and tunneling under the surface, and by the end of the war there was a small Nazi research base on the Moon. The free energy tachyon drive craft of the Haunebu-1 and 2 type were used after 1944 to haul people," materiel and the first robots to the construction site on the Moon.
When Russians and Americans secretly landed jointly on the Moon in the early fifties with their own saucers, they spent their first night there as guests of the.... Nazi underground base. In the sixties a massive Russian - American base had been built on the Moon, that now has a population of 40,000 people, as the rumor goes."

"According to Rutledge, Apollo 20's mission was to explore the polar region of the Moon, on its dark side, to investigate images supposedly taken by Apollo 15 of the area which showed what appeared to be a vast ancient city and a huge, miles-long crashed spacecraft.
Rutledge’s footage would be astonishing if true, as it shows both the alien city and a flyover of the cigar-shaped spaceship. The videos then cut to the Apollo 20 crew actually exploring the interior of the crashed ship, and perhaps most amazingly of all discovering the body of a human-like alien."

""Luna Base,” according to many UFOlogists is an newly discoverd ancient Alien base on the far side of the Moon (e.g., the side we never see). They say it was filmed by the Apollo Astronauts and a number of probes on fly by missions.. They also claim the base was an HQ for a massive mining operation using very large machines to likely extract valuable and rare particules found deep within the moons rocks."

"According to the UFO and alien hunters Mars Moon Space TV, in a video uploaded to YouTube on June 5, 2016, Johnston, who is well known in the UFO conspiracy theory community as a "NASA whistleblower," recently released a cache of old Apollo program photos from his private collection."
"When the conspiracy theorist Richard Hoagland first saw Johnston's collection of old Apollo mission images in 1995, he claimed that the photos prove that NASA's image technicians had been editing original copies to remove evidence of alien artifacts and bases on the lunar surface.
According to Hoagland, scans of Johnston's collection of photos from the Apollo program show structures on the lunar surface not present in NASA's scans of the same photos."
