First of all your logic is faulty because man could invent a false conception of a true God and still attribute true concepts to that false god. And second of all there are no "if, then" statements in the Declaration of Independence.
The princple that rights flow from God is both historical and present day American principle.
Now, if you think that needs changing, you can look forward to me fighting you every inch of the way.

No, I think it is still preferable that people believe in God, so long as they don't use that as a rationale to violence or as a means to impede scientific progress.
But the original interrogator specified that he wanted my own atheistic views regarding moral principles.
PS. My logic is never faulty. My premises might be on rare occasion. ;)
