In a godless universe, the concepts of morality, inherent rights, and human equality do not exist, except as delusional platitudes.
How can they?
Morality, to be a Real Thing, has to be imbedded in the psyche of man. With no Embedder, right and wrong are meaningless platitudes, invented by the whims of man, for manipulative purposes. In a godless universe, amorality, or whatever you want is all there is. Any attempts to 'standardize' moral codes are just arbitrary opinions enforced by power.
Human equality is a delusion, in a godless universe. Humans are just animals, at different stages of evolution, and the smarter and more 'fit' will be the ones to survive. Delusional, superstitious, and simple minded sheep are there to be exploited by the more highly evolved, advanced humans, and should be managed by the same. Power, deception, intimidation, brutality, manipulation, and anything necessary to achieve this goal is a positive. The ends justify the means.
Natural Law, like morality, can only exist as a Real Thing, if it was embedded by a Creator. An 'inherent right' carries with it an Embedder of these rights. The Enlightenment definition of Natural Law is the inherent right of everyone to life, liberty, and property. But in a godless universe, these are empty platitudes.. no Creator? No Natural Law. Rights are privileges granted by the ruling elite, and are not inherent.
America was founded upon principles that can only come through a Creator.
The 'self evident' truths that this nation was founded upon hinges entirely on them being embedded by a Creator, that EVERYONE senses, inherently.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government.. ~the Declaration of Independence
The foundations of America are premised upon a Creator, embedding Natural rights and equality. In a godless universe, the foundations of America are built upon a lie.. a delusion of equality and inherent rights.
