Why school was created and by who?

Why do we take our children to school to study useless things for 20 years of their life?

Who invented that and what is the goal of it? Have you ever wonder?

From everything you have learn in the school what you actually use at the moment?

Do they teach us how to grow our food? How to make our clothes? How to build a house?

They teach us about space, mathematics that we will never use, false history and false geography.

Just look at the map ONU is using on their logo and you will easily see that is different from what we learn in school. Why is that?
