China and India invented math. Arabs the modern numeral system--> 1,2,3,4,5,6,7,8,9 South America had aqueducts before the Romans. Actually, that's not true. The Romans had aqueducts in the first century AD. Peru didn't build theirs until 500 AD. Western Europe just stole it all and claimed it for themselves because no one could prove they didn't at the time. Now we can and we have. You were saying?
