According to Psaw there are dead Russians on the Moon, murdered by aliens who are still on the Moon.

The reality is that when the Americans won the race in 1969 the Russians ceased attempting to put a person on the Moon. Nobody from Russia has got to the surface of the Moon.

The distance from Earth to the Moon is 384,400 kilometres (238,855 miles).
For almost two-thirds of a century we have had the technology to enable us to detect the continuous presence of intelligent life on the Moon. On the surface there are small amounts of helium, argon, and possibly neon, ammonia, methane and carbon dioxide, which are not suitable for life. So life needs its own constructed environment, which would be obviously detected by our technology. Given that which we know from Earth-bound instruments and the vast number of craft sent to orbit the Moon from numerous different countries we can conclusively discern that there have not been aliens there in the past and there are none there now.
