But for our purposes on FR, the key one can be condensed into one line.
This is the atheist version (of necessity) of one of our founding documents:
"...endowed by with certain inalienable rights"
Cheers!
Easy, use the founding document that both the Declaration of Independence and the Bill of Rights were based on, the Virginia Declaration of Rights:
“That all men are by nature equally free and independent, and have certain inherent rights, of which, when they enter into a state of society, they cannot, by any compact, deprive or divest their posterity; namely, the enjoyment of life and liberty, with the means of acquiring and possessing property, and pursuing and obtaining happiness and safety.”
This proves that even among the Founders the concept stands valid without any creator. Where do you stand with the “key problem” gone?
