MY philsophy

In my philosophy of goverment essay i wrote that i belive that we do not need goverment.
but after talking to people and getting other opions i belive that it goes both ways .
i was writing stuff like back in the day the did'nt have goverment and they were fine.
Then i seen that the goverment and society is changing and we need rules to obtain these change.
Man grows an wonderful speeds and we learn something new each day.
