This introduction provides an overview of the cultural, historical, rand sociopolitical context of creationism in the US throughout the twentieth century. It introduces plausibility politics as a key concept for understanding why Answers in Genesis built the Creation Museum. Plausibility politics is the process of disentangling accuracy from reasonableness and the opening is leveraged by a group to advance its point of view. For many, this feels new. For seasoned political pundits and historians, it does not. It is a dynamic as old as the institutions and representatives entrusted to govern society. Yet it is not just media outlets, politicians, or scientists who attempt to persuade the public of their claims. Social movements, like creationists, seek to carve out a sense of plausibility for their own arguments as well. Being able to closely examine how this unfolds in a particular location, at the Creation Museum, affords a better understanding of how groups fight to stretch and expand what we, as a public, find plausible and later credible.
