Not really, those doofuses didnt leave us anything behind of worth or note. If they did exist, they were either spectacularly terrible at leaving low earth orbit, extra clean, lived like cats in the wild, and didnt fuck with making anything of note. In sum they aren't of note.

One of the best ways to find human settlements and artifacts is metallurgy (after its invented). Pure refined metals almost do not exist in nature, at least not in the earth's crust. Before that we look for rocks with tool marks, pottery shards, bones with teeth and tool marks, wood detritus arranged in patterns etc.

Of course we cant rule out something unknown. But based on what we do know it seems very unlikely that such an unknown could exist. There are definitely unexplained facts in history though so feel free to enjoy a flight of fancy. Check out Gene Wolf's Book of the New Sun trilogy. It's a great read set a few billion years in the future (dying earth subgenre of second civilization subgenre of science fiction) amongst a society that knows that dozens of rises and falls have come before and that they are not the weakest or the strongest or the best or the worst on any metric, least of all understanding.

Based on everything I have looked at I think there was an advanced civilization but its totally different than how we think it would be. Look at the 3 fingered mummy

What is this "everything" that suggests to you there was an advanced civilization before humans?

[–] CheeseboogersGhost 0 points 3 points (+3|-0) ago 

Pyramids. The saw marks in the stone. The Inca. The Aztecs. Oop Arts.

Probably but we're likely looking in all the wrong places to find them as it can be assumed that they'd want access to resources like water and food which are typically found closer to the coast than they are inland and oceans used to be about 120ft lower than they are today. That means ancient coastlines are now 120ft under the ocean and it's quite likely that any evidence of a civilization that lived there has since been eroded by waves and then buried under sand and mud.

It would be very interesting to search around the coastlines of the Mediterranean, Europe and Asia with ground penetrating radar though if I had the means I'd start at the poles. After reading about jews destroying artifacts found at the north pole and nazis seeking an inner earth culture at the south that's where I'd start for curiosity sake.

They've started burying that place under concrete for a tourist information center.

Think for yourself. Put in some research. Look in places you wouldn't normally think to look for that type of information.

Let's just say there are people whose best interest is getting you to believe what you are taught in school, 100% without question.

Was There a Civilization On Earth Before Humans? - The Atlantic

'It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far. '

'So, could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own?'

'If a civilization uses fossil fuels, the climate change they trigger can lead to a large decrease in ocean oxygen levels. '

'Civilization building means harvesting energy from the planet to do work (i.e., the work of civilization building). '

'In this way, a civilization and its demise might sow the seed for new civilizations in the future. '
