In a conversation today with a young person I discovered they had no idea why we celebrate the 4th of July. It's the celebration of the adoption of the Declaration of Independence. The thirteen colonies were already at war with Great Britain, but it was the official "Declaration of Independence" Perhaps we should go back to referring to it as "Independence Day" instead of the 4th of July.
"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.--"
Likely that's the most recognized line from the document. I suggest reading it.
