What country invented schools?

There's no single country that "invented" schools in the way we think of them today. The concept of formal education evolved gradually over centuries and in many different parts of the world.

While ancient civilizations like those in Mesopotamia, Egypt, and Greece had systems for teaching specialized skills or knowledge to a select few, the development of mass schooling as we know it occurred much later and involved influences from various cultures.

So, there isn't a definitive answer to the question of which country invented schools.
