A UFO hunter who scours images of space looking for evidence of aliens says he has found a "pyramid-like structure" on the surface of the moon.So-called UFO anomaly hunter Mark Sawalha says he found the pyramid on a NASA image taken close to the Eudoxus Crater. He revealed his findings in a YouTube video entitled "Pyramid on the Moon". He told Express.co.uk: "Here is a Pyramid looking object in the middle of Eudoxus Crater in a NASA Lunar Reconnaissance Orbiter (LROC) image on the Moon. "When I started to research this huge LROC map I found this pyramid looking object in Eudoxus crater. My fellow anomaly hunters have also found other objects on the same image." Mr Sawalha's previous findings include what he thinks could be alien craft, cubes, and other structures on the moon, and even buildings on Venus.Some conspiracy theorists claims the moon could be occupied by aliens and that is the reason NASA has not returned since the Apollo missions ended in the 1970s. They suspect findings such as this pyramid and other anomalies could be monuments built by an ancient alien civilisation similar to the pyramids and other structures on Earth. Similar anomaly hunters have found what they believe could be pyramids on Mars and other parts of the moon. One popular, but far-fetched, conspiracy theory claims our ancestors who built the pyramids were visited by superior aliens who helped them construct them. However, sceptics and NASA say the pyramid and other similar findings are just the effects of pareidolia – a psychological phenomenon when the brain tricks the eyes into seeing familiar objects or shapes in patterns or textures such as a rock surface. This would mean that the new "pyramid on the moon" could just be a misshapen rock.
