like this sentence "It was a landmark document and still remains the oldest written constitution in operation today. The United States constitution is the basis of all laws in the United States and along with the bill of rights it protects the freedoms of American citizens." &"Still many may ask why is this document so important? Why do we even have a constitution day? We have a constitution day because it is our responsibility to honor and respect our constitution.
The constitution defines how our government is to address the people of our nation it has checks and balances that are to control the actions of our elected and appointed leaders. " do i have to make any new paragraphs between these sentances and do i have to capitolize the word constitution every time i use it

Tnis is how it should be written:
"The United States Constitution is the basis of all laws in our country. Along with the Bill of Rights, it protects the freedoms of American citizens."
{I would take out the part about how people don't think that the Constitution is important. You have to be a brain dead sixth grader to think that the our Constitution is unimportant. Not that many people think that. You are making too much of a generalization when you say "many".}
"Our Constitution defines how our government addresses the people of our nation. To control the actions of our elected and appointed leaders, this document has checks and balances."
