Why is the world divided territorially?

After being faced with this question, I remember how the world map looks like. With all its curved and straight lines, boundaries between nations and countries are clearly seen. Every space owned is given a designated color to not confuse it with anything else. I have to say that the question above is valid. I began thinking what if the world is not territorially divided at all? What will happen? Will it lead to a better, more united earth or a more chaotic one?

We watched a video of the human evolution in our history class. It shows how early humans roam from one place to another to grow food. They treat the whole planet as their own. Wherever they go, they put their mark and for the meantime, they own the place. After being done with the place, they leave and go to another virgin land. I began to wonder: What if groups of modern people like us still live the same way?

I personally think that it might be a chaotic situation if ever we still live a roving life, without a sense of permanence or consistency. Imagine life just going around the country to have a source of food or business. Imagine fighting off other groups of people to get a piece of land for yourself. It can get a little tiring after some time. Territories are marked to give us some kind of organization. Countries had leaders and their own set of laws to have freedom for the people living there. Maybe it’s another characteristic of civilization. Maybe it is a part of development that we have to slice up the remains of the earth for us to all share. It gives us peace and order.
