The episode: "They have found that it is connected with the passage of days and the phases of the moon.It is,in fact,a primitive type of calendar.It has long been known that the hunting scenes depicted on walls were not simply a form of artistic expression.They had a definite meaning,for they were as near as early man could get to writing.It is possible that there is a definite relation between these paintings and the markings that sometimes accompany then." Why are there both present tense and past tense at the same time?
