You really don't have much to do these days do you BTFB!
 
No time at all, geologically speaking. Give it a million years or so and there will be very little evidence we ever existed. Sixty five million years on (the time since the dinosaurs became extinct) there will be nothing at all left. We aren't doing anything to this planet that it hasn't done to itself a hundred times over before.
