The main reason for friction is the roughness of the surface. When we see the surface of an object, it may appear smooth. but when we see it through a microscope. the magnified image will show a number of' tiny hills and valleys.

When an object tends to slide over another, interlocking of hills and valleys resist the relative motion and creates the force of friction. Smoothening the surface reduces friction. But if the surfaces become very smooth and flat, the friction from the molecular attraction becomes significant.
