“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.

Earth’s plate tectonics would effectively have “erased” the traces of a civilization that lived billions of years ago.
Venus is in the grip of a severe greenhouse effect and also undergoes similar “resurfacing” that would scour it clean of artifacts.
This leaves just a handful of places where archaeologists might find traces of a lost extraterrestrial civilization.
“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.

The astronomer suggested that very old spaceships could still be lingering in the Asteroid Belt or Kuiper Belt, a disc at the very edge of the solar system that’s made up of icy objects.
These artifacts are likely to be the remains of ancient probes, space bases or industrial facilities.
“In the case of a prior indigenous technological species, the artifacts might have had totally different purposes, such as asteroid mining operations or settlements on other planets and moons,” Wright wrote.
“Such structures would be expected to fall into disrepair, especially if its creators are absent.”
So where are these aliens likely to have come from?
Wright suggested they may hail from somewhere that’s very close to home.
The presence of intelligent life on Earth makes it more likely that ye olde aliens hailed from this solar system, rather than being descended from an “extraterrestrial species that crossed interstellar space,” he concluded.

That’s an incredible effect considering it’s from the mid 1950’s.
I hope trump can keep them out too.

Well, if it’s our solar system, dey bees home boys.
Venus was NEVER a greenhouse planet. There is very little free water in its atmosphere, and the average atmospheric temperature is over 900 degrees Fahrenheit, at which point water dissociates, creating free hydrogen, while the oxygen is taken up by various sulfur compounds, and the hydrogen quickly recombines into other substances or escapes to space altogether.
There may be enough of both hydrogen and oxygen to combine into a decent supply of water, once the planet cools enough, but until the heat is radiated off by some means, Venus is forever a stillborn twin of earth. The “cloud cover” is largely sulfuric acid, and most of the atmosphere is carbon dioxide.
You want a REAL “climate change project”? Terraform Venus.
OR perhaps we could just admit that “ in the beginning God.....”

Close enough!
I'm not sure he's from this planet. He looks like an alien (but so does Barack Hussein).
If aliens were as stupid as she is, they never would have survived their own stone age.
