"why does the world have borders?"

Once upon a time a long, long time ago there were no borders, just people living there life with no houses, no phones, and a lot of walking. All the people of the world were nomadic. All of these nomadic people kept on moving from place to place for what they need to survive. There were no walls or weapons because everything belonged to everybody. These people who lived a long, long time ago would move place to place for water, food, and everything else. Until, one day a man look at a plot of land it had all the livestock so he and his family would ever want so they would never grow hungry, it had a stream with enough water so that he and his family would never grow thirsty, and it had everything that they would ever need for forever and ever. So they stayed but then one day many moons later another family came and left a couple of moons later but this got the man thinking “what if…what if the next family wants to stay forever like us” everyday the man worried and then one day it hit him he would put a wall round the land so that everyone knew it was his. With that act walls soon became very popular everyone got one and soon there were arguments with neighbors like “your on my land…no your on my land” people wanted to protect themselves so then weapons were created and that started what we know to day as war. Not only that but soon clusters of these fighting people with similar ideas and enemies created large wall around them and called them borders. That is why we have border.
