Why is the world divided territorially?

In the beginning, God created man. And so on and so forth. But when Adam ate the forbidden fruit, they were thrown out of the Garden of Eden and were forced to live a hard life, where they had to work for food and they had to protect themselves. My point here is that even in the beginning, if you believe in the bible, there exist already the concept of territory. The Garden of Eden had its own territory and the place where Adam and eve was thrown to had its own territory.

Well of course at first, there were no specific and definite territories, only the concept remained. But as civilizations developed and populations grew, the world started to get crowded and it is inevitable for people to have some sort of means of order. So, as Elden mentioned some of the examples, there became territories. An example of having territories is losing them. Whenever certain states would conquer other states, the rights to the territories of the conquered state would naturally be given to the victor state. Through the idea of territories, order was maintained even during conflicts and wars. Another example was that after World War 1, as stated in the book. When the central powers lost the war, their territories were divided by the victors.

There are a lot of benefits in the concept of territories. They have strategic values for economics, politics and even science, as stated in the book. Benefits like having a territory with similar climates, landforms and bodies of water would mean that the government can apply certain adjustments for these differences to take advantage of these. For me, a benefit of having territories is that it would give people a sense of having a home where they would feel most comfortable. This is of course from my own perspective that is influenced by my course, psychology.

Good as territory may seem, there are also a downside for territory. One disadvantage is stated from the book where countries has less problems and are richer, that has less crimes and more jobs would be a hotter country for migration where as less fortunate countries that tries to go up would have their people migrating. This for me kind of makes things harder for the less fortunate people since people leaving these countries are bringing their skills and smarts with them that would mean that the less fortunate countries would have less means for development and the more fortunate countries would have more people to use for development that there would be other manpower that wont be used for development, waste of skills.
