I think the most successful civilization is Ancient Greece. We're still a part of it - it's just the homebase keeps moving around. We're a part of ancient greece. We're a part of the very same civilization. It started in Greece, switched over to Rome, then to Constantnople, then to Rome then quickly to Europe, then shared with the USA. I see it all as one very long lived civilization. == makes it easier. Then we've just got a few civilizations to worry about. Of course, due to exchange of ideas and commerce and politics and whatnot, even the split into "western civilization" and "eastern civilization" etc is kind of misleading as well. But it's a little better than how we normally break things down I think smile emoticon ==
