Why is the knowledge of medieval people about the world around them so different from the modern one?

The Middle Ages is the era of theocentrism, that is, only God stands at the center of the worldview of a medieval man. In the Middle Ages, people explained everything that happened on the basis of the divine principle. Everything that happens in the world is all thanks to the power of God. that is why the knowledge of medieval people about the world around them was so sharply different from the modern one. And in modern times, anthropocentrism reigns, that is, in the center of everything, there is man.
