What is the difference between civilizations of different historical periods?

There are differences between them in: cultural development, in religious views, in technological development, in moral and ethical development, etc. For example, in the era of ancient Rome and Greece, the person himself was very highly valued, that is, there was a culture of the body. The ancient Greeks and Romans erected numerous statues of deities and other prominent personalities, often in the nude. In the Middle Ages, there is a process of moral decline. In general, there are no individual values, only God is important, and people are insignificant creatures. Such orders were promoted by the Catholic Church.
