Architecture and engineering
Black people were the first to use the sciences of architecture and engineering, building some of the greatest and longest-standing structures ever seen. The Egyptians baffled the world by building more than 80 pyramids, with the largest, the Great Pyramid of Giza, covering 13 acres and made of 2.25 million blocks of stone. The Giza pyramid was built around 2580 B.C. and is still standing strong today.

Medicine/Doctors
Before the European invasion of Africa, black people had developed a medical system based on plants and herbs to cure illnesses. Egypt, Southern Africa, West Africa and parts of East Africa were more advanced in medicine than Europe at the time. They used plants with salicylic acid for pain, kaolin for diarrhea, and other extracts to kill bacteria.
The achievements by doctors in ancient Egypt were incredible. Findings obtained by archaeologists have produced evidence that in 3000 B.C., the Egyptians performed successful brain surgeries.
