Whether creationism should be taught about in school at all is a difficult one for me. I think LH's 1st argument is fundamentally flawed in that is seems to be saying that because there is uncertainty about the correctness of science and creationism both should be taught. But that doesn't follow: I don't know whether there will be a sunrise tomorrow or whether I will be alive tomorrow but one is much more likely than the other. Equally, in history we know that every account of a battle will be biased and partisan and so to some extent 'a lie': that doesn't mean we should teach any alternative account of the battle we fancy.

I'm much happier with LH's second post. Part of being an adult which a good education system should impart is the recognition that the world is more complex than you might think as a 7 year old. So someone studying history who is older than, say, 12 should be aware that there is bias in the accounts. Similarly, they should be aware many people believe in creationism and should understand what it entails. But they should ONLY be taught about it when they have reached a certain level of maturity (to be agreed) and preferably as part of a much wider review of belief systems.

What I am not in favour, though, is either pretending the belief doesn't exist or an ex cathedra declation creationism is wrong. For me the best place to look at it would be a course on critical thinking looking at creationism, dawkins and advertising campaigns studying not so much the truth or otherwise of the thing itself as the verbal techniques being used to persuade you one way or another
