Zero evidence of things like refined metals or synthetic materials in the geologic record makes the odds of an advanced ancient civilization seem highly improbable.

Yes, I've heard of refined glass as being one of the indicators. However, pretty advanced technologies like pottery would not have made it.

I can't be sure this [1] is the original article I was remembering but it might be an interesting read anyways. I am sure the study authors approach the subject with far greater care than I could.

I don't agree that pottery is "pretty advanced". It's just fire applied to clay.

Concrete, on the other hand, is advanced.

The novel "The Hab Theory" is a good story about the discovery of prehistoric civilizations.
