I have a question for any archaeologists we might have hanging around. Say that right now, instantly, every man woman and child dropped dead, but all of our artifacts and buildings and whatnot were left intact, and no other living organisms were affected. How long would it take before there was no evidence that man had ever existed without massive efforts being spent searching? Obviously there would be the odd fossil here and there that might last for billions of years, but they would be rare and hard to find. Where would our artifacts most likely endure the longest? I'm guessing in the deep oceans maybe?
It's kind of an odd question, but sooner or later we're either going to have leave this planet or die out. Assuming that the planet itself survived, for how long would anyone be able to tell we had ever been here?
