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.

I don't think you quite understand the scale of the conquests Alexander would need. India is much more densely populated than Persia and the humid environment makes the spread of disease much easier. Defeating some border kingdom wouldn't be enough to topple every warlord in India.
