The political founders of America had a deistic view of the "creator" which is why they said, rights derive from "Nature and Nature's God". Notice that "nature" appears twice, and the apostrophe ("Nature's") is possessive in the sense that the divinity is part of nature, not the other way around. If that were the case, they would have said "God and God's creation, the natural world".
The idea that to be human is to be part of government, flies in the face of logic and experience.
For instance, I am human and am not a government employee. I'm libertarian politically, and recognize that human rights are objective and grounded in human nature; not supernatural.
