ancient civilisations and empires in history

let's list 'em.
off the top of my head, there's ancient greece (philosophy! sculpture! tragedy!), rome (gladiators), the byzantine empire/constantinople (mosaics, awesome architecture), ancient india (uh.. elephants?), ancient egypt (pyramids and papyrus!) .. ancient china (vases, funny hats and robes), feudal japan (ninjas)

am I missing any? add please.

THE CIVILIZATION THAT MOCKED NOAH BEFORE THE GREAT FLOOD IS THE OLDEST, IF NOT THE OLDEST CIVILIZATION KNOWN TO MAN
