I'm just pointing out what the DOI states. The Idea Of America rest solely on the concept that man does not derive his rights from other men, but from a creator. My question to you is as an American Atheist, how and where do you derive your rights, since you do not recognize a creator?
This is the whole "experiment" America was formed around. It's ONE solid concept: Man does not, nor can he give the right of LIFE, LIBERTY, and THE PURSUIT OF HAPPINESS.
I've explained that so many times on FR I don't have the energy to go through that again, but simply put, my rights are mine due to society's agreement to respect each other's rights. There is no being that GIVES us these rights, humans in the course of creating societies worked through the ideas of liberty, freedom and human dignity. These rights that are "given" me could be wiped away instantly if the wrong people came to power in the society in which I live.
Man indeed formulated those rights. IMHO, of course.
