Bob Holmes imagines an earth without people in New Scientist. "All things considered, it will only take a few tens of thousands of years at most before almost every trace of our present dominance has vanished completely. Alien visitors coming to Earth 100,000 years hence will find no obvious signs that an advanced civilisation ever lived here."

Update: Derek Miller notes that even after human traces have vanished from earth, evidence of our civilization would remain on the moon and in space.
