article about thought experiment on pre-Human civilization, no evidence, just wondering how to look
So, could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own? Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. 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.
Given that all direct evidence would be long gone after many millions of years, what kinds of evidence might then still exist? The best way to answer this question is to figure out what evidence we’d leave behind if human civilization collapsed at its current stage of development.
considering the effect time has on *everything* can't help but think if there were a previous society, we'd never know.
and of course something might be buried under the ice in Antarctica

So, where are the examples?

Unless of course its below miles of ice within Antarctica. Or under thousands of feet of water covered in silt in the middle of the ocean.
Playing devils advocate here.
If something "external" decided to swing on by and shape early humanity. Maybe they had strict laws to not leave behind any technology that could potential advance what ever was here too quick. Maybe they got to a point where agriculture, math, and the basis of organized civilization started to form. Then they left. Taking with them all the tools they used to jump start whom ever was here.
Its all speculation. Time will tell. Either way.

An advanced civilization would most certainly leave behind evidence.
