The stone age people, modern humans like ourselves, that we’re searching for in the Goldsborough area could perhaps be called the “first British folk”. This was the time when the rising North Sea finally cut us off from the continent—Denmark, Holland and Belgium—drowning Europe’s “lost country”, Doggerland, and we truly became the British Isles that we know today, around 6400 BC. There was even a tsunami that finished off the job about 6100 BC, sending giant waves down the east coast and wiping out the last remnants of the lowland forests, rivers and marshes.
