Following is an excerpt from The Science of Evolution and the Myth of Creationism: Knowing What’s Real and Why It Matters by Ardea Skybreak, published in 2006.

It’s important to think about how you can tell whether something is really true or not. What are the methods and approaches which can be used for getting at the truth and distinguishing it from falsehood? Without a basic grasp of these approaches and methods it’s easy to fall into accepting just about any lie or falsehood, especially if it seems to be put forward with conviction by people in positions of power and influence (governments, religious authorities, TV personalities, and so on).

It’s good to have a critical mind and to question everything. But then again it’s also important to recognize when at least the basic truth of something has already been clearly established. If human beings always went around thinking that “nothing is ever sure,” how could we ever survive or get anything done? Should we walk in front of a moving bus because “we can’t ever really know for sure” whether we’ll get run over? Should we not bother setting an alarm clock because we “can’t ever know for sure” that it will ring, or that it even really exists, or that we really exist and have a reason to get up? These examples may seem silly, but they make the point that, even just to function in day-to-day life, we human beings really need to have some way, some approach and method, which can help us to determine when something is actually true (or false).

Of course we’ll never have absolute truth—in the sense that we’ll never know everything there is to know about everything—but we do have some means and methods for getting to the point that we can say, with a high degree of confidence, that something is true—meaning that it actually corresponds to some aspect of material reality as it really is.

Again, the point is that it’s good and important to question everything, but it’s also good and important to recognize that not everything is forever up for grabs—sometimes we can know enough about something to accept it as true, stop agonizing about it, and move on. Such is the case with the basic theory of evolution.

But a lot of people in the United States today still don’t realize that we can be that sure about evolution. Anti-evolution and anti-science Christian fundamentalist Creationists have worked to confuse people’s thinking on this since the late 19th century, typically becoming particularly active and aggressive in times of social turmoil and when the overall direction of society is being broadly questioned and debated. It’s especially at such times that reactionaries resist all forms of social progress and call instead for looking backward and “restoring core values and traditions.” Today is no exception.

The Creationists have waged such determined anti-evolution and anti-science campaigns in recent years that U.S. universities are now reporting that they are getting very worried about growing scientific illiteracy in the country as a whole as they notice that more and more freshmen are arriving on campuses so poorly trained in even basic science that they actually believe “the scientific community is divided on whether evolution happened” and that “evolution is still just an unproven theory.” To state it clearly again: both those notions are completely false. The scientific community (in the U.S. and worldwide and in every field of science) is not “divided” on the basic facts of evolution. The consensus is overwhelming that (a) life has definitely evolved and that (b) the basic mechanisms involved in how life evolved and continues to evolve (such as natural selection) are by now well understood.

The “Theory of Evolution”—What a Scientific Theory Is

As for the question of evolution being “just an unproven theory”: this is also false. As spoken to throughout this book, there is an incredible amount of accumulated and mutually reinforcing evidence for evolution, and the general scientific consensus is that the theory of evolution is among the best-proven and best-documented theories in all of science.

But one of the favorite methods of the Creationists is to play on people’s ignorance and confusion about some basic words: in regular everyday English, the word “theory” often means “a guess” or something that has not been proven to be true. So the Creationists hope that when you hear the words “theory of evolution” you will automatically think it hasn’t yet been proven to be true. But, in scientific circles, the word “theory” has a very different meaning: a “scientific theory” is what scientists call a complex body of thought that ties together a number of different ideas and proposals which successfully explain—from a number of different angles—the basic principles and mechanisms involved in a natural process, such as the origins and later change and development of some part of actual material reality. So, for instance, scientists talk about the “theory of gravitation” or the “Copernican theory” (of the motion of the planets, including the earth, around the sun) but that doesn’t mean they’re “guessing” that objects fall towards the earth because of the pull of gravity or that they’re “guessing” that the earth goes around the sun rather than the other way around. The theory of gravitation and the Copernican theory are by now well documented and supported by the accumulated scientific evidence, and the same can be said of the scientific theory of evolution.

Of course scientific theories are always being further extended and developed as human knowledge expands and comes to understand some things that we didn’t previously understand. And as knowledge develops, it is inevitably the case that some old ideas are discovered to be wrong and therefore need to be discarded. Science actually advances by calling into question and critically reviewing previously established scientific notions. It is true that there is always going to be more to learn and discover about everything. But that doesn’t mean that we can never come down and say that something is true. People who like to say things like “but you can never be sure” fall into the mistaken outlook and approach known as philosophical relativism. (Of course, since human knowledge is never complete and perfect, and is always developing, people who think and act like they have “absolute truth” about everything, or everything important, fall into the erroneous method known as dogmatism, which is the “flip-side” of relativism.) But when we say something is “true” it simply means that there is good, compelling and concrete evidence (preferably from a number of different and mutually reinforcing sources and directions) that our understanding of something actually does closely correspond to how that something really is in objective reality, that is, in the real material world—which includes all that is part of the natural world and which encompasses the features and workings of human social organization as well. (See “Reality and Distortions of Reality—Objective Truth and Subjective Influences” on page 216.)

Scientific theories (whether pertaining to the world of nature or human society) do not get proven to be “true” overnight. Before any great idea or set of ideas can be confidently said to be “true,” it has to get put through the scientific crucible—that means it gets poked at and critiqued and challenged and tested over and over again and from countless different directions. A good scientific theory puts forward some predictions about what we should expect to find in the real world if the theory is true; and it also makes predictions about some of the things we should not be able to find in the world if the theory is true. This is known as the principle of “scientific falsifiability”: a genuine scientific theory, as a matter of principle, has to be capable of being disproved by facts (things which, if discovered, would prove your theory to be wrong). The theory of evolution could be falsified (proven wrong) if, for instance, fossilized dinosaur and human footprints were ever found in the same undisturbed rock layers, because that would mean dinosaurs and humans lived at the same time, and this would completely contradict everything we know about how and when different species evolved. Biologists can give many such examples of the kinds of things that—if they were ever found to exist—would make a complete shambles of evolutionary theory. So, like all good scientific theories, the theory of evolution is falsifiable in principle—but, as a point of fact, science has never found anything (not a single thing) that actually falsifies it. It has, however, found many, many things that support it.

The theory of divine Creation is a religious belief, not a scientific theory. One of the sure signs of that is that the theory of divine Creation is, by its very nature and definition, impossible to falsify. The Creationists refuse to give people any examples of any kind of scientific discoveries that they could accept as proof that their divine Creation theory is wrong after all. They make a principle of this, because for them it is a matter of absolute religious faith. But if you make a principle of saying that there is no possible way that any information could ever come to light that would prove your theory wrong, then you are, by definition, not being scientific, and your theory has nothing to do with science!

Again, the theory of evolution was, from its very beginnings, falsifiable as a matter of principle. But as it turns out, all the actual scientific data that has been collected in the nearly century and a half since Darwin published his major work on evolution has repeatedly supported the theory of biological evolution; and none of it has ever provided evidence to the contrary. This more than anything is why there is such a broad and solid scientific consensus on the matter.


Throughout this book, it is has been shown, from many different angles and different sources, that evolution is a well-established scientific truth which is upheld and applied by the vast majority of scientists in the world. But just because something is true doesn’t mean it will prevail at all times, especially when people who hold false views are able to wield or influence the machinery of the state to spread and impose those false views. People don’t always think about this enough. For instance, in the United States today there are some people who understand that evolution is a proven fact but who think that it’s just a waste of time to worry about the crazy Creationists because, after all, they’re not going to be able to change the fact that evolution is true. They seem to think that, at least in countries like the U.S., society “will never go back to a time when most people didn’t know life had evolved through natural processes”—so why waste energy addressing the creationist lunacy? But in my opinion it’s a serious mistake to be complacent about such aspects of the “culture wars” in the United States. I’ve heard the same argument made about the anti-abortion movement. (“Don’t worry, these people are nuts; women in the U.S. will never have to go back to the days when abortion was illegal and women did not have the right to determine whether or when they would bear a child.”) Oh yeah? Well, look around you—one step at a time the fundamentalist religious forces have managed to chip away at women’s fundamental right to control their own reproduction and in some parts of the country (especially rural areas) it has already become a practical impossibility for many women. In regard to evolution, the same types of fundamentalist reactionaries have managed to confuse a lot of people, take over school boards and even get disclaimers inserted into high school science textbooks, telling people that evolution is “controversial” and “an unproven theory” (it is not!). So why is it so hard to imagine that these people could make even further headway, especially when their right-wing political programs are the order of the day in the highest reaches of government?

And it’s not like there isn’t still a strong material basis for lots of people to be ignorant and confused about this. Looking not only at the U.S. but at the world as a whole, it is still the case that tremendous numbers of people have never been taught even the most basic facts of evolution (many have never even heard of it!): most believe instead one or another myth or superstition about how all the plants and animals and people came to be. Furthermore, the aggressively expanding Christian fundamentalist movement is a well-funded and well-organized movement which gets significant financial and ideological backing from conservative and reactionary political organizations. Evangelical and fundamentalist Christian movements in the United States in particular are closely allied with the political Right and growing fascist trends and developments (think back to the Santorum Amendment, for instance). Thanks to this support, Creationists have significant and regular access to mainstream media, where their viewpoints and activities are often reported uncritically and as straight news. They also own or control a lot of media outlets themselves: their radio and TV programs, books, pamphlets, museum exhibits, professional-looking web sites (just do a web search for the word “creationism” or look up the web sites of the ICR [Institute for Creation Research] or the Discovery Institute) now reach (and no doubt confuse) millions of people. They have money and other resources that allow them to regularly send speakers on tour to address school boards and parents’ groups, to speak on college campuses and in courtrooms, and to address Congress and other government officials. And, as pointed out before, they have powerful ties right up to the highest levels of the ruling class in American society.

Can a well-orchestrated and well-funded propaganda blitz in itself “reverse” the truth of evolution? Of course not. But it can do a lot of social damage by training legions of people (including the young and inexperienced) to firmly and zealously believe in completely wrong ideas and to increasingly reject not only evolution but even science more generally, as a method for learning about things and for transforming the world.

Of course the government, military and big corporate sectors themselves have to regularly make use of actual science to carry out their objectives (they need science to help them wage their wars or develop new pharmaceuticals, for instance), so they are not about to throw all science out the window. They will need to allow at least some people to continue to be trained in actual scientific principles and methods and to learn some actual truths about the way things are in reality—otherwise they could not continue to function and to enforce their rule and domination in the world. But that doesn’t mean they have to let everyone in on it!

For one thing, reactionary political forces have always found it useful to try to pass off as genuine “science” all sorts of completely false and non-scientific beliefs when it helps them to justify a reactionary political agenda: it should be enough to think for a minute about all the phony “scientific” theories of supposed racial or gender inferiority (phony “science,” which rested on absolutely no legitimate scientific evidence!) which have been used repeatedly to buttress and justify such things as the horrific enslavement of Africans, the Nazi extermination of Jews, the countless forcible restrictions on and coercion of women, and so on. So just because an idea is not true, and a whole lot of people know it is not true, doesn’t mean it can’t be put in the service of concretely aiding some very bad things!

In short, don’t underestimate the damage that can be done by the unchallenged promotion of wrong ideas, especially when they are being presented as “scientific.” What the Creationists of different stripes are doing by packaging their religious beliefs as “science” is not just trying to make their beliefs more acceptable to a somewhat scientifically oriented public, or trying to get their religious teachings into the public schools even though the Constitution is supposed to guarantee that people in the U.S. are not subjected to the imposition of religious doctrine and the tyranny of religious clerics and diktats. What the creationist program is also doing is working to undermine science itself—the whole method of science and the whole way science trains and encourages people to learn about everything in the world (and also how to change it) through a process of systematic and repeated observations and interactions with the material world as it actually is.

If the creationist frontal attack on science itself were ultimately successful it would set science back literally centuries and limit us to trying to understand and affect the world (or passively accept the way it is) on the basis of superstition and belief in the supernatural.

So what can people, in particular those who are not professional scientists, do to better understand what is wrong and untrue about what the Creationists put forward? The accompanying insert, “Some Things You Can Do to Learn More about Creationist Lies and Distortions” on page 222 offers some suggestions and indicates important sources of information.

DONATE to the revolution.

From the genocide in Gaza, to the growing threat of world war between nuclear powers, to escalating environmental devastation… the capitalist-imperialist system ruling over us is a horror for billions around the world and is tearing up the fabric of life on earth. Now the all-out battle within the U.S. ruling class, between fascist Republicans and war criminal Democrats, is coming to a head—likely during, or before, the coming elections—ripping society apart unlike anything since the Civil War.

Bob Avakian (BA), revolutionary leader and author of the new communism, has developed a strategy to prepare for and make revolution. He’s scientifically analyzed that this is a rare time when an actual revolution has become more possible, and has laid out the sweeping vision, solid foundation and concrete blueprint for “what comes next,” in the Constitution for the New Socialist Republic in North America.

The website follows and applies that leadership and is essential to all this. We post new materials from BA and curate his whole body of work. We apply the science he’s developed to analyze and expose every key event in society, every week. posts BA’s timely leadership for the revcoms (revolutionary communists), including his social media posts which break this down for people every week and sometimes more. We act as a guiding and connecting hub for the growing revcom movement nationwide: not just showing what’s being done, but going into what’s right and what’s wrong and rapidly learning—and recruiting new people into what has to be a rapidly growing force.

Put it this way: there will be no revolution unless this website not only “keeps going” but goes up to a whole different level!

So what should you give to make 2024 our year—a year of revolution?
Everything you possibly can!
DONATE NOW to and get with BA and the revcoms!
