Ancient Egypt lasted for thousands of years and it existed concurrently (at the same time as) with lots of other civilisations such as Ancient Sumer, Indus Valley, the Shang Dynasty, the Ancient Greeks and the Ancient Romans. Because Ancient Egypt existed at the same time as these other civilisations, they had contact with many of them through trade and war. The pyramids that Egypt is famous for were built in the earlier part of its history, from around 2630 BC to around 1525 BC. The timeline above starts at 3100 BC when Egypt came together and ends in 322 BC when Alexander the Great (a Macedonian/Greek general) invaded Egypt and it started becoming more Greek.
