Rock is a very poor conductor of heat and there is quite a lot of it between the surface and the mantle. As a result heat conducts to the surface very slowly and quickly radiates into space. As a result the vast majority of heat at Earth's surface comes from the sun. The heat from the mantle is felt at erupting volcanoes where magma, which ultimately gets it heat from the mantle, reaches the surface.
