The Romans were pretty civilized for their time, but the British are civilizeder. That's a real word.
The Romans didn't have no cable TV, and the British barely do. That's one for the Brits. Rome didn't invent punk or heavy metal music, England did. That's two and three right there. We're going to leave tea out of the equation, since the Brits stole it from China and the Romans stole it from I forget who but they definitely stole it, so it's still Rome 0 and Britain 3. The Romans never kicked the USA's butt and England did (yes they did, look up who burned the White house), so that's 4 to zip for England.
The English did not, however, kill any major religious prophets, and the Romans did. Then they officially started an entire church dedicated to the guy they killed. For creating an entire religion alone, that's one for the Romans. Yes the English split off from their church, but no points for that. Just like the tea thing, stealing stuff doesn't count.
So far we're 4 to 1 for Britain. It's a tie for the Roman chariot vs. any English car, also for having a language that lots of people still speak. I'm not even going to touch feeding people to lions vs. One Direction, because both are pretty horrible.
