This scientist believes aliens may have existed in our own solar system

Is there really life out there in space? This scientist thinks it existed closer than we think. As in, right here, in our own solar system. Extraterrestrials may have harbored and lived on a planet within our vicinity, even our own planet Earth.

Astrophysicist, Jason T. Wright believes that aliens lived on our surrounding planets before vanishing forever.

He speculates that the life forms existed millions of years ago.

In "Prior Indigenous Technological Species," a scientific paper published at Cornell University, Wright says, "Here, I discuss the origins and possible locations for technosignatures of such a prior indigenous technological species." He continues, "...which might have arisen on ancient Earth or another body, such as a pre-greenhouse Venus or a wet Mars."

Obviously, there aren’t any extraterrestrials living among us now. Wright informed The Huffington Post that scientists have searched the solar system robotically. However, his research and his interests lie in a species that may have utilized technology the way that we do. He wonders if there are any remains or artifacts that could help scientists uncover an answer to previous life in our solar system.

He says, “My guess is that we can rule out big swaths of the Earth’s history. The farther back you go, the harder it is to rule something like that out. If they’re very old, there may not be any traces. Things don’t last long. If you put something in orbit around the sun, it’ll be subject to collisions with asteroids and meteors."
