We arrived in the last hour and trashed the place....

You might have seen something like this before - it's more or less to scale. That little red line at the end of the top part is "Quaternary". You'll have to click on the picture and zoom in to see it. The Quaternary is 2.5 million years long, but modern human are only in the last 200,000 years and recorded history the last 3% of modern human existence.
So, yes!.. basically we arrivedin the lasthour - at the last minute, and trashed the place.
Edit: Oops, minutes not hours.
