Western civilization: Important societies

I like all,

Greeks gave us epic poetry, philosophy, history, music theory, the democratic system and they had great artists.

The Romans also had artists just as good, but they had better architects: they invented mortar, the arch, the vault, the dome. They projected and implemented vital stuff like the aquaducts, viaducts, stadiums. They had a great knowledge on how to run a state (but had a lot of terrible emperors) and they left us with Roman Law. Also their language stands at the foundation of a lot of modern languages.

The French shown a lot of style, and later even had some great artists. The women in Paris and France in general are the most beautiful I've ever seen.

The English had Rock, Prog and English Humour, so they win.

I'd put Greece and Rome on pretty even footing. But Greece did a lot of things first whereas the Romans copied them and improved on their ideas. So Greece it is.

Teeth? Yes I know we have dodgy teeth, agreed.  Thats cos we've got more important things to think about than what our smiles look like.    I notice the questioner didn't even concider the USA in his list. 

England of course  hahaha.  I can here my neighbours (Scots, Welsh etc) just seething with rage over this question!  Ha ha!  Anyway the Brits invented : Prog, Football (The original not what the Americans laughingly call football) (The one EVERYBODY else plays), the sandwich, TV, etc Oh and Cricket ha ha.  What did the Romans do for us?

Greece, if only because they got 90% of civilized society right, and then we spent the next 2000 years f**king it up and rebuilding it.

Erm... Italy, France and England are all, to differing extents, pieces of the Roman Empire. Some were peripheral, others were central. The development of modern nation states in these zones is fairly recent (mere centuries), and if we rewind 1,500 years, the British isles consists of a slew of warring tribes, France consists of Franks and other tribes and Italy just barely saw the end of the Roman Empire at the hands of the Goths. Ultimately, I think you should've broken this up into two questions: which ancient civilization did more, and which modern one do you see as most important.

USA! USA! USA!
