This is mildly off topic, but I disagree that Egypt was "the most influential" civilization. Practical geometry was primarily an Ionian invention, whereas the Egyptians used it for agricultural and religious purposes. The later, at least somewhat more unified Greeks provided a massive framework for which modern civilization is based off of. The Roman Empire is still affecting the world today. The Moors in Spain gave us access to the Greek knowledge, gave us a need to bathe, desserts, and three course meals. China gave us innumerable technologies here in the west, Italy in the Renaissance gave us perspective, accurate ballistics, and the understanding of surface area in terms of how it changed the speed of boats, Germanic states in the same time period gave us Protestantism and the idea that the government is above the church, and England produced the magna carta, the precursor to modern democracy. How is most important being defined here? Is it most technological contributions? Because that's all China. Most legal precedents set? Rome. Most cultural influence? Greeks. Most behavioral/values? Victorian England. And this is really just the west; the only reason I'm including China in there is because China has given the world vast amounts of technology that it didn't use nearly as effectively as the Europeans and has had such a massive influence on technological development its absurd. Egypt is important, yes, but the most important?
