"And if someone could explain how The Ten Commandments are the basis of the Constitution I'm all ears."
John Quincy Adams, Sixth President of the United States: "The law given from Sinai [the 10 commandments] was a civil and municipal as well as a moral and religious code; it contained many statutes . . . of universal application-laws essential to the existence of men in society, and most of which have been enacted by every nation which ever professed any code of laws." -- Letters of John Quincy Adams, to His Son, on the Bible and Its Teachings (Auburn: James M. Alden, 1850), p. 61
Joseph Story appointed to the Supreme Court by President James Madison: "I verily believe Christianity necessary to the support of civil society. One of the beautiful boasts of our municipal jurisprudence is that Christianity is a part of the Common Law. . . . There never has been a period in which the Common Law did not recognize Christianity as lying its foundations." -- Commentaries on the Constitution of the United States; and 1829 speech at Harvard

Those are general statements about the need for the populace to have a religious foundation since the Constitution itself is secular. The actual content of most of the Ten Commandments, three of them about monotheism others about not coveting your neighbor's goods and respecting your parents...are not to be found any documents of legal standing in the United States. Unless you're just looking at it as an early example of 'Law Giving'. In which case the Code of Hammurabi and the Magna Carta are bigger influences.
