The Declaration of Independence appeals to God as does every, single State Preamble:
From Truth Or Fiction:
The Fifty States Reference God in their Constitutions-Truth!
And here is the proof (I'm sure you'll find a way to call me a liar like Barton but facts is facts dude):
God in the State Constitutions - The U.S. Constitution Online - USConstitution.net
So what?
The Declaration of Independence is not a legal document. From the perspective of the British, it was a treasonous document.
Don't your gods have enough to do without you having to spackle them into every gap?
Push a button did I?
Hoping to falsely portray the DoI for something it is not are you?
