Which civilization, China or Rome, has had the greatest impact on humanity?

China was too isolated from the rest of the world until a few centuries ago, for it to have much influence on humanity as a whole. True, a number of important technologies like gunpowder, paper, printing and the compass were developed in China, but, China’s isolated geographical location, largely cut off from the rest of the world by great oceans, deserts and mountains, narrowed China’s capacity to influence the world directly. It’s only now that China is fully integrated into the world as a whole, and, we’ll have to see the long term effects of that fundamental change. For most of human history, China existed as a kind of alternate reality, an exotic locale that had only indirect effects on the rest of the world. In contrast, Rome formed the basis for European culture, and, for centuries, Europeans ruled the world. Most of modern science, law, language and culture is derived from Greco-Roman society.
