Rome: The World's First Superpower

In many ways, this is a week done documentary series but I can't get past the first error in the title. It makes me doubt the validity of everything else mentioned. While Time was a superpower, it definitely wasn't the first. Not in any particular order, but Egypt, Babylon, the Medes and the Persians, the Greeks under Alexander the Great, and even the Hittites all preceded the Roman empire. All of these were known as great superpowers who had conquered much if not all of the known world of the day. I understand most people do not no much about the Hittites but they were powerful enough that other major power signed peace treaties with them to avoid going to war with them until internal conflict destroyed them. I mostly mention all of this because if you're going to teach something is history, we need to teach it correctly. Well not as great as some of the other superpowers mentioned above, even the Assyrian empire predated the Roman empire. At least be accurate. I could even handle if you wanted to say that the Roman empire was the greatest superpower ever, even though personally I disagree with that belief.
