How exactly does a "Creation Museum" meet the qualifications to be defined as a museum?

Is this not a contradiction of terms? And if not, what exactly makes a creation museum, a museum?

The word museum, is defined as “a building in which objects of historical, scientific, artistic, or cultural interest are stored and exhibited.”

I’m not so sure a creation museum meets that criteria. I’d love to hear your thoughts on this issue.

FYI: this is not an attack on Christians, but simply an inquiry to why a creationist exhibition is defined as a museum
