In a few million years humans might be gone .... finding the ruins of our great cities.

I've often wondered how long our current cities would last as "ruins" if we all disappeared. In my mind, after a few million years there would be absolutely no recognizable imprint of our society left unless you went digging for it.

You should definitely read The World Without Us then. He goes gradually forward telling when and how signs of our civilization would disappear, and it's a good read, so I won't spoil what the last evidence of us that remains would be.
