It is an interesting stone isn't it? The other take on it is that the cup marks may represent star constellations. Speculation about 'religious' practices is just that - speculation. However,I think it is fairly safe to say ancient peoples marked the turning of the year (solstices/equinoxes) and studied the constellations - which would have been so very much more visible to the naked eye than in general today.
