The Ancient Africans contributed to many ideas that we use today. For example they use willow as a pain/ headache remover and we used that idea, but instead we use Advil. They also made the sundial as a clock, they had 12 spaces acting as 12 hours, the stick on top would have a shadow that points to the hour in the day, the next day it would start over. They also learned about the milky way and plotted the orbits in the system correctly which helps us know whats up in space and where we are "labeled" in the galaxy. The Ancient Africans could make tools that helped them in the everyday work life. That helped us model our everyday tools off of the tools they made to help them.
