Today we are talking about the Ancient Egyptian pyramids. Ancient Egypt is located in Northeastern Africa along the Nile River. It lasted for over 3000 years from 3100 BC to 30 BC. Fun fact for all you trivia people – this makes it the longest surviving civilization in history. During this time, Egypt was a leading cultural and economic influence in North Africa and parts of the Levant. It was ruled by 170 Pharaohs, and left behind many monuments, including pyramids and temples, as well as hieroglyphic writings. The civilians, rulers, languages, writing, climate, religion, and borders changed many times over the millennia, but Egypt still exists today. The pyramids of Ancient Egypt still continue today, but the question remains – how were these magnificent pyramids built? Their construction, especially the great pyramid of Giza, is one of the most fascinating and enduring mysteries of ancient engineering. There are two major theories that have been discussed. One is that they were put here by the aliens, along with the Egyptians. Two is that slaves actually built the Egyptian pyramids.
