Hm, I think we have to be a bit careful about the legacy of the classical world being "interrupted". This may be true in part (wasn't it that central heating was lost to Britain even though it had been known in Roman times?), but contrary to popular belief, the middle ages were in many respects also a continuation of the classical world.
For one thing, the Eastern Roman empire continued to exist until the 15th century and it is there that e.g. the Justinian code of law was devised, which, as far as I know, is still the basis of many modern legal systems, while itself being built upon ancient Roman law.
But even in Western Europe, Christianity can be seen as a continuation of the Roman Empire: It's not as if the religion hadn't been substantially changed and "romanised" after Constantine made it state religion. Also, in terms of scholarship, many key classical philosophers / scientists were never forgotten; Aristotle in particular remained a key influence. And, contrary to popular belief, middle ages scholars knew perfectly well that the earth was round, as had been shown by Ptolemy and others before him (they thought it was at the center of the universe, but as far as I know, nobody had successfully proven otherwise in antiquity either).

I agree with you. We have to be careful, and the middle ages were in many respects a natural development out of the classical world.
But they were a natural development that saw a radical upheaval in the culture. The organization that the Romans put in place largely fell apart, forgotten. Industrial production crashed. There was not a continuous transmission of tradition -- a large part of the Renaissance really was reading ancient texts to discover what they said. They had vanished from the living tradition.

That's not something that -- to the best of our knowledge today -- it's possible to prove or disprove. (Similarly, if you conceive of "the earth" as the spherical surface rather than the solid ball, you'll be perfectly correct if you say that Rome is at the center. You'll also be correct if you say any other point is the center.)
What evidence we do have, interestingly enough, points towards the earth really being at the center of the universe. Redshift in every direction! We reject that conclusion for philosophical reasons, not because it's been disproved.
