The earliest known humans arrived in these lands around 900,000 years ago. During this time there were huge changes: the ice covering Britain melted; instead of hunting all the time, people learned to farm and make metal tools; they found time to worship. There is still evidence we can see around us today, such as Stonehenge, long burial mounds and hill forts which are thousands of years old. This, before the Romans invaded is often called prehistoric.
