YE OLDE ALIENS Ancient ‘spacefaring aliens’ may have lived in our solar system billions of years before humans, scientist suggests

Academic says advanced extraterrestrials could have thrived on Earth, Mars and even Venus - before disappearing without a trace

THE SOLAR system humanity calls home may have once been inhabited by an extinct species of spacefaring aliens, a top scientist has suggested.

An American space boffin has suggested ancient extraterrestrials could have lived on Mars, Venus or even Planet Earth before disappearing without a trace.

In a fascinating academic paper about “prior indigenous technological species”, James T. Wright from the Pennsylvania State University raised the fascinating possibility that evidence of these extinct aliens could exist somewhere in the solar system.

Wright is an astronomer who received global attention after suggesting an “alien megastructure” had been spotted in orbit around a distant star.

Now the stargazer has said advanced aliens may have left behind “technosignatures” for us to find – if only we knew where to look for them.

“A prior indigenous technological species might have arisen on ancient Earth or another body, such as a pre-greenhouse Venus or a wet Mars,” he wrote.

However, most of the archaeological evidence of an ancient civilisation would probably have been been lost.

Earth’s plate tectonics would have “erased” the traces of a civilisation that lived billions of years ago.

Venus is in the grip of a severe greenhouse effect and also undergoes similar “resurfacing” which would scour its land clean of artefacts.

This leaves just a handful of places where archaeologists might find traces of a lost extraterrestrial civilisation.

“Remaining indigenous technosignatures might be expected to be extremely old, limiting the places they might still be found to beneath the surfaces of Mars and the Moon, or in the outer Solar System,” Wright added.

He said alien evidence was likely to be buried beneath the ground, allowing it to survive asteroid impacts.
