This timeline takes us on a whistle-stop journey of life on our planet. We travel from the Big Bang, 13.8 billion years ago, to the time of the dinosaurs - and on to the evolution of the first humans and the creation of the first written records, around 5000 years ago. It's a time known as prehistory.
