Some. Ish. We aren't EXACTLY sure on the half-million years tag. But a bloody long time indeed.
The oldest structures may fall away but traces remain. Roman forts long gone can been seen from the air ala time team. Dave- you want it- no buildings left gone, or GONE gone.
If the former, then 8-10,000 years from today. If the latter- mmmmnnnn. 25,000. Give or take a few.
