How did the Egyptians feel about the world around them?

The ancient Egyptians believed that they lived in the best country in the world. And for a long time this was probably true. At least we can say that Egypt was one of the most developed countries of the Ancient World. The outside world of the Egyptians was practically not interested and they had a very weak idea of ​​it. In particular, when the Egyptian troops left the Euphrates, they were unspeakably surprised to see the river flowing from north to south. The ancient Egyptians had a very arrogant idea about the culture of other peoples; for a long time, foreigners were not even considered people. Although later the attitude towards them began to change, especially when mercenaries from other nations began to be recruited into the Egyptian army.
