Can someone give me the answer in their own words in a youu plz

We should have the Constitution because it has been used to govern our country for more than 200 years. It is the fundemental source of our laws, our rights, and our freedoms. It helps to keep order within our government and our country. The Constitution is also a "living document." This means if something isn't right, it can be appealed for a change. The Constitution holds dear to what an American is, to what the United States is.
