 Around 8,000BC Britain was still part of the European land mass and communities of Middle Stone Age people migrated to England and began to inhabit the North York Moors.Relics of this early hunting, gathering and fishing community have been found as a widespread scattering of flint tools and the barbed flint flakes used in arrows and spears.By 5000 BC global sea levels had risen, the North Sea existed and Britain was cut off from mainland Europe.
