Isle of Harris Scotland has the oldest rocks in Europe, some over 3,000m years ago which is around two-thirds as old as the Earth itself. Lewisian Gneiss is the most common and was formed from volcanism and bending and stretching of the Earths crust then exposed by glaciers, oceans and weather. Stanley Kubrick’s 2001: A Space Odyssey used Harris as a backdrop for Jupiter. Yup, outta this world!
