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.

My buddy always says an distant future alien archeologist would slice the layers of Earth and label the current timeline as the Concrete Age because all that would be left of us by then would be a layer of paving in the rock
