"Almost exclusively? Wow. So by you're own observation Christ is never mentioned, but Nature's God (a Deist reference) and Man's Creator (another Deist reference) are mentioned solely in the Declaration of Independence. There's also a mention of Devine Providence, yet another Deist reference. So how then do you make the leap to conclude this nation is founded on Christianity?"

Those words were written by Jefferson a known deist who was also known to attend only Christian churches. He is also considered to be one of the most intelligent men who ever lived, well versed in astronomy and holding the largest library in the world on geography and the natural world. I would not attempt to put him in a box as he was a very pragmatic person that defies stereotype.

"They also brewed their own beer and distilled their own liquor; was this nation founded on alcohol as well?"

Pretty much, water was so suspect in those days alcohol was part of the daily ration considered mandatory for members of the military. The Virginia gentry would start drinking shortly after lunch and many would be staggering drunk by dinner, it was considered normal in the day. The views on drinking then are much like they are in modern day Japan. Jefferson had on of the largest and most worldly wine collections know at the time.
