think it would be more fun to try out aboriginals, mauri, maya, or eskimo civilizations. but there are resons why these civilizations never raised to stand the test of time, or to make significant contributions to world history. look at europa today as an exsample, we could name countless nations who have come and gone, but these are nations, not civilizations as such.
in europa we basically have 3 civilizations. the anglo-gemanic, the latin-hespanic, and the slavic.
so very diffrent in language, genetics, and cultur as they possibly can be, in such a small spot, thou woven together.
maybe within the next 100-200 years we will have the emerging of a hole new civilization called the intra-euro civilization, but it will still consist of thous 3 civilizations, no regards to religion.
a 1000 years ago we had the same 3 civilizations who have spawned from 3 diffrent parts of europa, the roman/greek-interrelation, the saxon-anglo-interrelation, and the bysantine-russian-interrelation.
the roman/greek-interrelation kicked the north-african malineese-cartegarian-interrelation out of spain, or we would have had 4 civilizations in europe.
(sorry to the turks, who are of persian-arab-interrelation, (we still love you guys

)
so what civilization were the original european people you might ask... -the oldest civilization on the european penesula are the greek, they were the first people to develop what we would accept as "civilization", and as such the mother of all the european tribes. while most of europes tribes was making stone weapons, greeks were melting bronze. when Athens, Sparta, and Tyre were build, most other european tribes were emerging from the stone age. most likely tribes that orginally had spawned from the greek civilization.
