I went back and looked again. It says after 1,000 years, "MOST brick, stone and concrete buildings gone," which sounds reasonable. We don't have *that* many buildings that are older than 1,000 years. And then it says after 50,000 years, "Mankind's tenure is mostly marked by a few archeological remains," so there would still be traces of some buildings.
