What is the likelihood there was once another advanced species on Earth on par with us millions of years ago, but there is no surviving remnants?

There was a race called the Azbel, which got wiped out 20,000 years ago.

I would say very low. And my evidence is that we don't have any evidence of a mass extinction event before this one caused by something other than widescale seismic or heavenly cataclysm - in other words: not caused by a single species. And since Earth has been a Savage World since the Cambrian destroyed the utopia of the Ediacaran, I doubt it could have produced an enlightened species during that time frame.

That's not millions and those were just humans when they were the least degenerate.

read this if you want a serious answer or google Silurian Hypothesis if you want a popsci version

You would detect them by seeing a mass extinction event. There is no evidence of life complicated enough to build cities or spaceships or anything like that before the cambrian and everything after the pre-cambrian is savage, which means the planet didn't have the capacity to produce an civilized species that DIDN'T wreck the planet, only something like humans, so the answer is almost certainly a solid: "NO."

Sure? That fits with what I posted though.
It's just a hypothetical that end's with it being highly unlikely, we probably wouldn't find a lot of shit since it would decompose, but some stuff like irregular nuclear radiation from the civilizations nuclear waste might give us a hint.

None, otherwise we would have found their trash and broken appliances.

Intuitively, relatively high. The reset and mudflood people have added to some very interesting points and ideas to the anomalies I'd noticed throughout my life. I also grew up wondering whether humans, or some subset of humanity, came from Mars or another star system. Along with spaceship moon, etc.

Just because we`re causing an extinction doesn`t mean it`s a trait common to all intelligent civilizations.
For all we know, an intelligent species with different breeding habits, dietary needs or lifespan may develop a society that is smaller and less intrusive on the environment.
