This is a little book about the history of us - humans - people living on a small rock which is flying around a bigger shiny rock, which by some, almost magical, powers - moving towards an unknown destination. You reading this right now is an amazing achievement in itself; You were the fastest sperm, you survived your toddler years, and learned to read as well. You are great, and you are a big part of our combined history as species. Most people think of history as a series of events that happened in the past. History is more than that. It is the story of how those events came to be. It is the story of the people and the cultures that created them. It is the story of how we've all changed and how we've all stayed the same. History is important because it helps us to understand the present. It gives us context for the things that are happening around us. And it helps us to see how we can make a difference in the future.
