Metamorphic rocks were originally igneous or sedimentary rocks. They were altered by being involved in an episode of mountain building, buried deep and subjected to immense pressures and temperatures. In effect they were the roots of the mountains.
Later erosion over millions of years removed most of the mountains leaving the altered rocks for us to see.
