Yeah,right, but then..Where do my inalienable rights come from??
A random sequence of proteins in our DNA -- the "inalienable sequence".
This isn't going to be a popular answer, because many view the *words* of the founding fathers as almost on par with scripture, but....
We don't have truly inalienable rights in the descriptive sense - they only exist in the normative sense. What are rights? They're duties imposed on another actor - when those duties are observed then rights are *conferred*. Rights are not created without someone else first observing their duty. God has no duty to me and cannot confer rights to me - only my fellow human being can do that. My rights to live, liberty, and happiness are not because God is observing his duty, but because my fellow man is. When my fellow man stops observing that duty then I most certainly lose the rights conferred from that duty. My rights are protected by the state through their use of police power. God does not ensure that my rights are upheld, not in this lifetime - and that's the one I'm personally interested in. I have a wife in this life - and I want her rights and my rights to be respected in this life. And this is accomplished by the state through the creation of laws and penalties.
If/when someone fails to observe their duty and infringes upon my rights then the state intervenes and imposes a penalty on the transgressor (and hopefully the threat of this penalty will prevent one from transgressing in the first place). But without a state to protect my rights, it does me no good for those rights to be called "inalienable" - because I can most certainly be alienated from those rights as soon as the contract with my fellow human beings breaks down. God doesn't enter into this equation, there is no contract bebcause there are not two parties involved who can represent themselves plainly.
