Should national monuments be recognising creationism as a viewpoint?

The National Trust has included references to creationism in its new visitors centre at the Giant’s Causeway. The Giant’s Causeway is a world heritage site in Northern Ireland. It is an area of 40,000 interlocking basalt columns, which according to science was the result of a volcanic activity about 60million years ago. However the National Trust seems to imply that this is still open to debate.

After an exhibit showing the historical debates over the formation of the causeway "This debate continues today for some people, who have an understanding of the formation of the earth which is different from that of current mainstream science. Young earth creationists believe that the earth was created some 6,000 years ago. This is based on a specific interpretation of the Bible and in particular the account of creation in the book of Genesis. Some people around the world, and specifically here in Northern Ireland, share this perspective. Young earth creationists continue to debate questions about the age of the earth. As we have seen from the past, and understand today, perhaps the Giant's Causeway will continue to prompt awe and wonder, and arouse debate and challenging questions for as long as visitors come to see it."

The National Trust has confirmed that it as an organization accepts the scientific position and defends its decision its decision by saying “Central to everything is how the Causeway was formed and the National Trust position is that we believe and accept the mainstream scientific idea that the causeway was formed by volcanic eruption 60 million years ago. In the scientific and formation elements we base everything on fact. It's a fact today that there is still a series of debate surrounding the formation of the Causeway but the exhibit is about that debate of how the causeway was formed.”

Should an organisation like the national trust be giving the creationist side of the argument alongside mainstream science?
