If you want to dispense with a Creator God then say goodbye to your unalienable rights, endowed by a Creator.
“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."
This declaration is the foundation of American liberty for if Creator-endowed inalienable rights are disavowed, then all human rights are in the grant of government and can be as easily revoked as awarded - a recipe for tyranny.
