Because the efforts of the alchemists to create gold were what led to modern chemistry.
But the bottom line is, you CAN'T create gold from non-gold, except by manipulating atomic structure. That is now accepted as fact. End of story. Just like evolution is accepted as scientific fact. End of story. (the arguments that it is not accepted in fact, are proposed by people entirely outside the field of science, or by charlitans making money from fools)
What if I went into teaching, wouldn't I be a better more prepared biology teacher if I knew what the competing theories would be from some of my students and their parents ?
The author of this article doesn't tell us if the woman taught an opinion one way or the other about the theories. The assumption is made that just because she uses "critical thinking" in title the point of the course was to trash evolution. I for one find it difficult to believe that a critically thinking student of science would conclude creationism makes sense. I can't get there from here using critical thought and I happen to believe that God created the world.
I didn't read about the professors book tour in this article.
