As long as it has been investigated scientifically, then "Absence of evidence is not evidence of absence" is actually not correct. To my understanding that is exactly how particle physics research is conducted.

My understanding is that there is no evidence for pre-historic human societies that had advanced technologies. We have hard data in our genetics for the timeframes of human existence (statistical rate of random genetic drift vs nearest ancestors) in addition to the fossil record, we have good information from ice cores about when/what of particulates were in the atmosphere, we know general rates of tectonic movements , and it's easy to observe what's under kilometers of strata with drilling cores if anyone has a good hypothesis as to where to drill.

But also untouched. Maybe we'll find a way to dig up evidence in the future...

Is there such a thing as "evidence of absence"?

It's called a contradiction and it can only exist in the realms of logic.

I'm thinking that would be demonstrating that there cannot be evidence.
