Is there anything in the Declaration of Independence and US Constitution that forbids a theocracy?

HIM:

My understanding of Marxism leads me.to believe that you believe that doctrine of equality, social justice and universal sameness among humanity's diverse ethnic groups, in that we all have the same desires, dreams and vision for the future and each individual has inherent, equal worth. I dont believe that is true for an instant. You seem to advocate a totalitarian vision that all of humanity can aspire to if people would just submit to secular Koranism. Culture and heritage dictate otherwise. Western Civilization began its downfall with the ideas of egalitarianism, liberty and the brotherhood of humanity. Here we are.

ME:

Can you give an example of "universal sameness"?

What is totalitarian about anything I have proposed?

Isn't America founded on the ideas of the French Revolution?

What do you consider to be the Golden Age of Western civilisation?

Isn't the declaration of independence an assertion of equality?

Do you consider any theocracy to be by definition totalitarian? 

Are you an atheist?

Doesn't the declaration of independence assert the existence of God who created Man equal? 

What do you as an American have against equality? 

Are you aware that the First Amendment is based on Quran.com/2/256 which Jefferson read? The White House Koran is his. 

If the American Declaration of Independence explicitly referred to God who is believed to have self-evidently created Man equal, would it not be logical to assume that a theocracy was being envisaged after the Americans declared independence from Britain after rejecting the authority of the British monarch with a republic?
