Children should not be taught nonsense?
This seems a sensible proposition until you come across examples such as Santa Claus, the tooth fairy, estwhile bottom of the gardeners, witches, monsters...
... the fact is human beings and not just children are natural magical thinkers (magical thinking is a fundamental belief that a) the universe should revolve around me, why else is it here? and b) I can control the universe although I sometimes have to do bizarre rituals in order to establish that control) and as real scientific thought takes considerable effort with little or no emotional impact, it is generally rejected.
It is much easier to do something wrong but which appears to deal with the situation and how I feel about it than to do something right. Magical thinking is a way of dealing with stress, not just sorting out stressful situations. But it helps e.g. to misquote (in all likelihood) Cromwell 'Say your prayers and keep your powder dry' i.e. carry out a stress relieving ritual and simultaneously do what you really need to do.
So, bizarrely, it is easier to believe that the world was made in 7 days (try it for a few days) than that it took 15.4 billion years to come about. It also relieves stress because it allows human beings to wrap the universe around them like a baby blanket. it's small enough to think about therefore it is small enough to be controlled.
Should creationism be taught in classrooms. Yes, but not as a serious contender, but as an example of the contrast between scientific thinking and magical thinking.
Paris... because she makes me think magical thoughts and go through bizarre rituals.
