The chinese gave the europeans the compass and paper which lead to exploration of the world.The Greeks gave the europeans grids to organize cities. The Romans gave aqueducts for water. Mesopotamia taught people to make bronze and Gold. and The egyptians made linen out of flax that was traded. OH yeah, I think the Greeks were the first to use indoor plumbing. One more thing, the Chinese were the first to use paper money and the europeans learned form that.
