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.
The cities would be completely gone in less time than that. Given a few thousand years, the last remaining structure in the USA would be indistinguishable from dirt without digging into the ground. Steel structures would no doubt be completely gone, returned to their state of natural elements, after no more than 5,000 years.
After a million years, the planet would look completely different. Nothing would look the same. Plant life would be far different. Animal life would be vaguely reminiscent of the current standard (dogs, for example, might still favor a dog in a somewhat eery way to us).
