That school of thought dates from the 18th century when thinkers appealed to a Creator who endowed those rights (even if it was a rather aloof Deist conception of God). However, in the following century it faced strong competition from the utilitarian school that suggests that rights are only a convenient fiction that society recognizes for the common good. Plus, these days ever more people do not believe in any particular Creator who could have endowed anyone with rights.
Human ethics, metaethics and politics is definitely nowhere near "laws of physics" settled and agreed on.
And I guess you can argue that some do not recognize universal rights, but it's not a compelling argument to just point out what some people think.
What is it in human nature that concretely and morally entails our having rights? the faculty of reason and its crucial role in human life, as long as we are free to act according to our thoughts. No faith involved, no mysticism required.
[added] The Founding Fathers did not create a theocracy. I don't see what point you are trying to make -- the concept of natural rights does not require a god, and it is irrelevant whether some person invoked deism or not. The fact is that we are all born with inalienable rights by virtue of our nature, what we are and how we ought to live together.
The Greeks may have had a concept of natural rights separate from their being endowed by a Creator, but that is not the same concept of natural rights that John Locke proposed and which inspired the American Founding Fathers, leading to posts from Americans like the one we see above. Advocacy for that school repeatedly cites the existence of a Creator.
That writers continue to conflate the definition of legal "law" with scientific "law" is in some ways amusing, but it weakens the analogies. A physical theory (testable hypothesis making specific predictions) isn't a law. The analogies aren't merely suspect, they are often fatally flawed with appeals to authority amongst other practices which are not relevant in science.
What I am saying, more simply is that "laws" of physics aren't facts. Using them as the basis for an analogy results in flawed reasoning.
With regard to the original subject matter, fundamental rights mean different things to different people, countries, governments, and other entities. It would be nice if everyone adopted a single minimal definition that we all interpreted and supported in the same manner.
This wish is unlikely to ever be fulfilled, as fundamental human rights often run counter to power structures of various types across the world. These rights could potentially constrain other entities rights, so they may choose to adopt some or none of them, or interpret them in as wildly different a manner as they wish.
This is vastly different than how physicists interpret and test theories. We don't set h_bar == 0 because we don't want the world to have a quantum character in some locations. But entities in power can set FundamentalRight_type == 0 for a specific type (pick speech, life, liberty, pursuit of happyness) if they so choose.
In this way, "fundamental" rights are really not so fundamental. They aren't like the theories of physics, the same everywhere.

Facts are what they are, regardless of what people may say or feel about them. The laws of physics, such as Ohm's Law, can be discovered and are facts even were people to deny their validity. The same is true for all facts of nature, including the nature of humans and their rights.
The fact is that I'm a brain in a jar, therefore you don't really exist and have no rights whatsoever.
For what you say to be fact, and not just your personal belief wrongly presented as such, you first need to prove to me that you really exist.
All this to say, anyone who claims to know the "truth" or "facts" in a discussion about ethics and morals doesn't know what they're talking about.
Fact in law is not the same as a fact in science.
Scientific "law" is an artifice, more of something created by someone attempting to explain using a poor mapping of language to the way scientists do their work. Scientific theory makes testable and falsifiable predictions. Gravity is a theory, not a law. It makes testable and falsifiable predictions.
Specifically, Newtonian gravity, what you call the law of gravity or a "law of physics" is known to be wrong.
Given this, how can you claim that they are what they are "regardless of what people may say or feel about them" ?
As a (non-practicing Ph.D) physicist, I have this discussion with many non-scientists, to try to help them move beyond the concept of "laws of physics" (there are none), and into the concept of testable predictions arising from the hypotheses in the theory.
Ohms "Law" is yet another example. Ohm's law breaks down spectacularly for certain materials under specific conditions. Quantum systems like Josephson junctions most definitely do not obey Ohm's "law".
In science, absolute laws do not generally exist. Using your words "regardless of what people may say or feel about them", they are irrelevant, and often incorrect. Scientific "law" is not absolute. They are not "facts".
Language, english or otherwise, is a very poor substitute for the language that testable hypotheses are written in. There is often a fundamentally severe impedance mismatch between what is written out, and what the language of science (mathematics FWIW) actually says, or even how to interpret or describe what is going on.
Without constructing a strawman, I'd like to point out that in previous centuries, people were so enamored of the fixed natural "laws", that they actually persecuted those who poked holes in them. One that comes to mind is the geocentric model of the universe.
This one is particularly interesting, as it had both religious overtones and support, and made specific predictions. The predictions of geocentricism about other planetary orbits did not match observations.
That is the fundamental Ptolemaic system law of planetary motion was wrong.
But it couldn't be.
But it was.
So astronomers developed modifications to the laws. Epicycles were invented.[1]. Which made the calculations harder. And it meant you had to discuss a mechanism by which this worked. That is the law which you are claiming to be inviolate, must be modified at best, or discarded at worse.
Add in to this very accurate measurements and analysis by Brahe, Kepler, and others, this lead Galileo, Newton and others to formulate a new model of the solar system, backed up by testable predictions. It took a while for this "law" to supplant the previous "law". But supplant it, it did.
Because science is not based upon absolute, legalistic versions of laws. Science is based upon testable hypotheses. If the tests fail, so does the hypothesis.
This mechanism survived unscathed for about 250 years or so. Until Einstein pointed out the problems with it.
My point was simply that just because the popular science writers call it a law, doesn't mean it is a "law".

In point of fact, the majority of the battles the US military and ARVN engaged in were against the NVA (North Vietnamese Army). That is, conventional forces vs other conventional forces. While the VC (VietCong) were very active and played a crucial role in the eventual victory of North Vietnam over South Vietnam, they were never the primary military force deployed by the communists.
Moreover, the VC were not just guys with AK's. They had the full panoply of military hardware that light infantry uses: from anti-tank rockets to mortars to light anti-air missiles. The VC even had a few tanks. The VC did not engage solely in small unit guerilla operations either. Once in a while, they would launch major offensives using coordinated assaults of 10's of thousands of soldiers.
What history has shown is that while insurgencies can cause problems for established regimes, without outside logistical and financial support (i.e. supply of arms, food, money, etc) they usually cannot win.
If we have the right to life, we have the right to self-defense. If we have the right to overthrow tyranny, we have the right to fight it and install a new form of government.
