Linguistic Archaeology: That first city

The most influential city in human history will be the very first city we built. Sure cities have been bigger and snazzier since that first one but that first city defined the way cities are for every city that followed. We might never know its name, nor where it was, but we know it existed. 
What do we know about that first human city? Not Rome, nor Athens, nor Jerusalem, nor Babylon but they all have aspects of it.
