The Ancient River Valley Civilizations created many things that affect us today. Each place has affected us differently. Those civilizations created technology, writing, government, trade, farming calendars and many other important things we use today. In ancient Egypt they used hieroglyphics as communication. Hieroglyphics are a system of writing based on pictures which were carved into clay or stone but could also be written on papyrus. Farmers in Egypt created many systems of technology to water their plants using water from the Nile River. These forms of technology included dams to move water, reservoirs to collect water, and shadufs to raise water from pools. Both of these things in history have affected us very much in the world today,
