SF on Tech Civilization Before Ours
August 2, 2012 4:17 PM Subscribe
I'm intrigued by the notion that our civilization is not the first technological civilization to arise on Earth. After all, our ancestors several tens of thousands of years ago were as clever as we are.
I'm looking for SF treatments of this notion. Recommendations?
Non-fiction claiming to evaluate actual evidence of such a civilization is welcome, too.
