"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."--
Why do we celebrate today? We wouldn't be if it weren't for a document called the Declaration of Independence. This document changed history. This document is how we became a nation. It represents a birth and a separation. Very much like a baby when the baby grows up and moves away from his parents. The ties are still there but the baby has gained independence to live his/her own life.
