The reason why the Constitution is the most important event in history is that with it, the U.S maintains its order. It does so much that we don't even realize how much of an impact it has on our government and ourselves.
Firstly the Constitution created the three branches of government. The Legislative, Executive, and Judicial branches. By creating these three branches this helped decrease the risk of tyranny again, as well as help creates balance. As we have seen throughout history, an unbalanced government leads to a chaotic country, a country that no one respects, and most countries look up to us as the great big brother. So, when you think about it, the Constitution helped us gain respect too.
Secondly, the Constitution outlines our freedoms. It gives us the power to express ourselves selves, and honestly, it gives us the green light to be ourselves and be proud of who we are and the country we represent. It also gives us security, the security to know that we have a voice and are free to use that voice legally
In conclusion, the Constitution's creation was the most important part of history because it's what made this country what is today.
