Meh. I'm not impressed. I was taught to believe in Santa Claus and the Easter Bunny, but the skepticism that resulted when I figured out the deception ultimately challenged the religious beliefs my family raised me with, too. Of course, exposure to the religious beliefs of the ancient Egyptians, Greeks, and Romans helped, too.
I suspect that some people are naturally skeptical. They question authority and make up their own minds based on their own observations and evidence. Along with that, a larger number of people are ... gullible. They are easily swayed by authority and are more susceptible to social pressures to conform. Whether they believe in creationism or evolution, the problem isn't what they believe, but the way they accept such beliefs without question.
I toyed with the idea years ago that the Middle Ages and centuries of persecution of skeptics as heretics provided a evolutionary force that marginalized people who carried genes that contribute to skeptical thought -- ultimately leading to a population prone to believing what they're told.
