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.

Earths 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 thats 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 thats 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.

Out in the holes where the Heechee hid
Out in the caves of the stars
Sliding the tunnels they slashed and they slid
Healing the Heechee hacked scars
We’re coming through
Little lost Heechee we’re looking for you
Sadly, only the “B” Ark made it here to Earth and survived.
And why is this not in “Breaking News?”
Hmmm....erased all evidence on earth. How convienent...
And nothing in orbit? Nothing on the moon? Not even a monolithic black rectangular box?
In before the “I’m not saying it was aliens, but it was aliens” guy.
Aliens may have existed in our solar system long before us
And greased pigs may have grown wings and flown to the moon to eat all the green cheese.
What is this, Fiction treated as Fact?
Sounds like a Movie Script.
Anything left on the moon would be there for millennia unchanged. Similarly, anything left on Mars.
Something tells me if we haven’t found it we won’t find it. But then again, any excuse is a good excuse to put boots on the Martian ground.

Fascinating how people can believe in aliens yet deny the existence of God and spiritual beings.

He’s avoiding the bigger problem of explaining how these previous civilizations evolved taking into account what we know about our own evolution.
Okay, where did the aliens come from? Other aliens?
Then where did they come from?
At some point, there is a starting point.
