We can see some prominent features on the surface of the moon. This is an edge of lunar crater on Mare Moscoviense and enlarged image below showing some kind of artificial objects and looks like artifacts. Shadow of the structures can be seen easily on the surface opposite to the direction of sunlight. It is sure these features cannot be rocks as such things are dotted all over the mare mascoviense in different shape and sizes. See this link : Mare Moscoviense An Alien-base
