Prior Indigenous Technological Species? (REDUX Originally Posted 4/27/17)

A space scientist has suggested ancient extraterrestrials could have lived on Mars, Venus or even Earth before disappearing without a trace.

In a fascinating academic paper about “prior indigenous technological species,” James T. Wright from 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 civilization would probably have been lost.  Fist tap Big Don.
