The results of a Gallup poll regarding creationist numbers were released on December 17.
First the bad news. Forty percent. That's the number of Americans who believe in a literal 6-day creation, a global flood, Noah's Ark, that snakes can talk, and that goats get their stripes because their parents had their way with each other in front of a row of poplar rods. Some still believe that the earth is flat.
Now for the good news -- acceptance of evolutionary biology is rising while the number of creationists slowly falls.
The evolution/creation "controversy" is a misnomer because it's been a beatdown in every sense of the word. When a creationist asks for evidence of evolutionary biology, they have that evidence handed to them by the boatload. But they summarily reject it because they're too afraid to honestly look at the evidence and admit that they're wrong. Conversely, when you prove to them why biblical creationism is wrong, they simply regurgitate the mantra "You're misinterpreting things," or "You're taking things out of context," or spout some other non-sense about things they don't understand.
It's not that creationists are too stupid to understand evolutionary biology; it's that they're blinded by a dogmatic worldview that doesn't require evidence -- only faith. As Youtuber AronRa stated in his video series, Foundational Falsehoods of Creationism, in order to be a creationist you don't need to know anything about astronomy, physics, biology, chemistry, mathematics, genetics, plate tectonics, meteorology, paleontology, taxonomy, zoology, optics, or even geography. Creationists choose to remain willfully ignorant, and that, to me, is worse than stupidity. What makes things even more irritating is that they claim to know science better than scientists do.
Ask a creationist on the spot what a theory is, and they typically can't answer you. Ask them what genetic drift is and they'll give you the deer-in-the-headlights look. Ask them if an alligator and a crocodile can mate and they'll shut right up. Ask them to tell an astronomical unit from a light-year, an allele from a zygote, an atom from a photon, a monotreme from a marsupial, or a quasar from a red dwarf, and they'll usually panic. Most creationists believe that evolution is not science, but when you ask them how it's not science, they'll squirm as if they're in a dentists chair having a root canal.
The evidence continues to grow in support of evolutionary biology by leaps and bounds. It is the foundation of modern medicine, food production, and forensic science. More people are waking up everyday from their dogma-induced stupor, observing evidence and realizing that they have been lied to for years. If creationists wonder why that is, and why atheism and agnosticism are on the rise, they only have themselves to blame.
So, if you're a creationist, keep it up. In the long run, you're only doing science a favor.
