You could research for yourself.
Even though the Greeks and Celts have been using moderately sophisticate plumbing systems before, the Romans perfected it. I've once that the water consumption in Roman Cologne back then was equal to that in our times!
Most Democratic Governments today, including the US, are based on Roman models of governance.
Most legal systems around the world are based on the Jus Romanum, the Roman law originating in the Twelve Tables.
Most languages spoken on Western Europe descend from Romance, which descends from Latin, and which has a vast influence on English.
Romans invented our calendary, which with some changes is still in use today (you owe "July" and "August" to two well known figures).
Romans used the writing I'm using now, practically in the same way
Romans had probably the best road building technology of the Ancient Age and made numerous contributions to the field
Romans also invented concrete, which is used until our days for... your house and pretty much everything you see on the street
blah blah blah see for youself: http://www.mariamilani.com/ancient_r...inventions.htm.
It's actually very obvious, glaring and even overwhelming. Many things were also originally Roman, and do not fall into the general misconception you expressed here. Romans not only perfected many and many previous inventions but also had a fair share of their own, and what you could expect from a large Empire.
Moreover I think their biggest contribution was political thorough and thoroughly. Without Rome, the Papacy would probably never exist, and Christianity would never prosper inside the relative safety of Imperial borders, furthermore they played a part in the migrations of the late Empire that more or less composed the entire ethnic makeup of modern Europe; Romans also introduced new species of plants and animals into Europe during and before the Empire and were the first ones to make a systematic industrialized approach towards agriculture and mining that set them apart in efficiency, and which are more or less adopted in our industrial economies.
Etc.... etc... etc...
