It would be okay if they were taught as THEORIES but I don't think the distinction is made that they are just THEORIES. I really don't think most teachers, particularly at the grade/middle school level, even remotely grasp the concepts they are teaching, and thus get them wrong, and teach them wrong.
The result is a whole legion of idiots who don't know what the hell they're talking about, but THINK they are superior. It's laughable, but sad at the same time. I'd rather have outright retards populating the citizenry than pseudo-educated loons.
Evolution is a fact and a theory.
Evolution as theory and fact - Wikipedia, the free encyclopedia
Paleontologist Stephen Jay Gould writes, "Evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air, pending the outcome. And humans evolved from ape-like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."[2]
Similarly, biologist Richard Lenski says, "Scientific understanding requires both facts and theories that can explain those facts in a coherent manner. Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change."[6]
Biologist T. Ryan Gregory says, "biologists rarely make reference to 'the theory of evolution,' referring instead simply to 'evolution' (i.e., the fact of descent with modification) or 'evolutionary theory' (i.e., the increasingly sophisticated body of explanations for the fact of evolution). That evolution is a theory in the proper scientific sense means that there is both a fact of evolution to be explained and a well-supported mechanistic framework to account for it."[20]
The comparison to gravity is perfect. You have evolution and gravity, and you have theory of gravity and the theory of evolution.
It makes just as much sense to deny gravity, as it does to deny evolution.
