According to Duncan Lunan, an alien probe has been orbiting the Moon for over 12,000 years. This is evidenced by repeated radio echoes with logical delays, on the same wavelength. The deciphered message contains an image of the constellation Bootes and the star Izar (Boo). The star Izar is over 200 light-years from Earth.
From Wikipedia:
“Duncan Alasdair Lunan, born October 1945, is a Scottish author with emphasis on astronomy, spaceflight and science fiction, undertaking a wide range of writing and speaking on those and other topics as a researcher, tutor, critic, editor, lecturer and broadcaster. He is known for his science writings as well as for his work on the Sighthill stone circle.
His 1970s report of a possible space probe orbiting around the Moon sent by the inhabitants of a planet orbiting Epsilon Boötis brought him to international notice.
In a 1973 article in Spaceflight, a magazine published by the British Interplanetary Society (BIS), he said he had identified and deciphered a hidden radio message sent by an alien space probe that had been caught but overlooked in the late 1920s by a collaboration of Norwegian and Dutch researchers who were studying the long delayed echo effect. Published along with an accompanying editorial disclaimer, Lunan maintained that the putative message came from an object at the L5 point in the same orbit as the Moon, sent by the aliens living on a planet orbiting Epsilon Boötis.
He came to the conclusion that the message was, “Start here. Our home is Upsilon Bootes, which is a double star. We live on the sixth planet of seven, coming from the sun, which is the larger of the two. Our sixth planet has one moon. Our fourth planet has three. Our first and third planets each have one. Our probe is in the position of Arcturus, known in our maps.”
The claim was reported in Time and the CBS Evening News. It was included in Rod Serling’s 1975 TV documentary In Search of Ancient Mysteries and, many years later, on George Noory’s Coast to Coast AM radio show. The alleged message has been refuted and in 1976 Lunan withdrew the theory, presenting proofs against it and clarifying what had led him to formulate it. However, in 1998 he re-interpreted part of it, claiming support from positional astronomy.”
According to Lunan, Daniken, and likely many other ancient alien theorists, the alien probe could contain data on the presence and intervention of an alien, more advanced civilization on Earth, their interference in our development, and much more.
Considering the 12,000 years the probe may have been in orbit around the Moon, this data could contain information much older than what archaeologists have managed to find, decipher, and translate so far.
There is no physical proof that the alien probe is in our solar system, but the hypothesis is very compelling, and the materials found in the probe could upend our historical knowledge of Earth and the origins of Homo sapiens.
