There have been many human civilizations on Earth, but the exact number cannot be accurately calculated due to the lack of accurate fossil evidence. Some studies suggest that the earliest human civilization on Earth appeared in Africa about 20 million years ago, while other evidence suggests that human civilization once appeared on other planets such as Asia, Europe and South America. According to different studies and perspectives, the number of times human civilizations appeared might also be different. However, no matter what, there had been many human civilizations on Earth. The development and evolution of these civilizations had a profound impact on Earth's history.

There had been five human civilizations on Earth. According to archaeologists and historians, the origin of human civilization could be traced back to the ancient Egyptian civilization around 20000 B.C., followed by the ancient Greek civilization, the ancient Roman civilization, the medieval European civilization, and the modern American civilization.
