there is another document
it begins like this....
The Unanimous Declaration of the Thirteen United States of America
When, in the course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the laws of nature and of nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
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...
The constitution is the supreme law of the United States, not the Declaration of Independence.
The Declaration of Independence has had no legal power or authority since 1789.
Actually, the original Declaration of Independence reads,
"The unanimous Declaration of the thirteen united States of America"
although you will sometimes see it printed the way you posted it.
Those uncapitalized letters in the original DOI are important and reflect the relationship between the independent states at that time. There was no United States of America in 1776.
See: The engraving of the original DOI by William Stone as commissioned by John Quincy Adams or this official transcript of the DOI at the US Archives. Supposedly, it took Stone three years to carefully engrave his "exact" copy of the original DOI.
