If humanity ends tommorow, how much time will it take to erase all evidence of humans or any kind of clue relating it to humans?
If humanity disappeared right now, how much time would it take for every evidence of our existence to disappear from the face of the Earth?
Hypothetical scenarios: What would happen if humans disappeared from Earth? When do you think humanity will become extinct? Will the humanity become extinct? When will we become extinct? When I can expect the human extinction? When will humanity end? How close did humans come to extinction? How many years do you think humanity will still live? How long will it be before the earth will not be able to sustain the human population? How will human beings on Earth come to an end? If all the humans left the earth and came back after 100,000,000 years would the chimpanzees/monkeys have evolved and built technologies like ours? How long until the human race will go extinct? What would happen to the internet if everyone in the world suddenly disappeared? Will humans eventually become extinct? What happen if water disappeared from the earth for 5 sec? How soon and by what means will the human race become extinct? When will the human race stop destroying earth? Could a civilization more advanced than ours have existed on this planet millions of years ago? What evidence could we use to rule out the possibility? When will the earth die? Is there any possibility, that human beings could live on another planet? If yes, how much time will it take to take all humans on that planet? How long can earth sustain humanity? Does evidence exist that shows human activity/existence goes back further than 6,000 years? Will humanity exit the earths orbit in the next generation? How and when will humans likely become extinct? What can we expect to happen to humans in 1,000  years? If wiping out human existence would save planet earth, and not doing so would lead to its complete destruction, should we do it? Will mankind ever travel back and forth through time? When will the last human on Earth die? What if we weren't the original people of earth and we killed off a race to have earth? Is time travel into the past theoretically possible? If one could could travel into the past, would dead people exist again?
