well that is a really hard question but for now I am going to go with the Greeks so much of modern thought originated with them and their influence made the Romans what they were. I mean just some of the things they brought the world includes, modern map making, Democracy, Cranes, modern mathematics, pi, paved streets (Romans took it further and created roads), more advanced gears, the alarm clock, the dry dock, tumbler lock etc the world just wouldn't be the same without them and the modern world certainly wouldn't be as it is today. But then again just go back to an older civilisation and they influenced the Greeks ect so I guess the first one is the real answer.
