To be pedantic, the Roman Empire did not fall in 472. It lived on in the eastern Mediterranean for another one thousand years. The Eastern Romans even took back a fair amount of western Roman holdings for a bit. The people who actually killed the Roman Empire were the Franks, permanently weakening it during the Latin occupation.
The Catholic church is an institution of the Roman Empire, and it's still around. That puts things in perspective, I find, and makes me wonder if 100 thousand years from now, historians will just lump the Romans and us into the same bucket.
