What will be our archaeological legacy?
Here’s the scenario: you are an archaeologist, 20000 years into the future. You know that your civilization has evolved for approximately 5000 years, as determined by recorded history, and you have achieved a world-wide civilization, with high technology. There is no concrete evidence of any type of civilization before the current one, but there are a lot of unknown “mounds” (actually massive landfills or trash heaps) from what are considered “prehistoric” (by your standards) societies. What would survive that you and your colleagues find in these mounds?
