Before we can begin to study the first peoples, it is important to establish the concept of time. Historians use timelines to help aid in the understanding of the time frame in which the topic under study has taken place. The first step is to establish how the past is organized into sections of time. The organization of time into Eras is a choice made by historians. The sections of time that are being used in this book are divided by major turning points (big events that change humans forever) in history. This book is organizing the major Eras into the following four categories: Prehistory, Ancient History, Middle Ages, and Modern History.
