The theme of the museum is captured in this paragraph from their home page:
Prepare to Believe
The state-of-the-art 70,000 square foot museum brings the pages of the Bible to life, casting its characters and animals in dynamic form and placing them in familiar settings. Adam and Eve live in the Garden of Eden. Children play and dinosaurs roam near Eden’s Rivers. The serpent coils cunningly in the Tree of the Knowledge of Good and Evil. Majestic murals, great masterpieces brimming with pulsating colors and details, provide a backdrop for many of the settings.
Creationism is a theory not supported by most mainstream Christian churches.True enough, I suppose, but there's a problem. Creationism is not a theory, not in the scientific sense of the word. For scientists, a theory is a set of interconnected hypotheses that describe and/or explain some aspect of the world. The hypotheses must be logical, falsifiable, and above all constructed from the analysis of data collected by way of systematic, objective investigation of the empirical world.
Creationism is what some of us call a folk model or even, in our more charitable moments, a folk theory. Most all cultures have one or more; for summaries of some, see here. The Judaeo-Christian version was made up by the more creative members of a tribe of pastoral nomads some thousands of years ago, perhaps assisted by heat, thirst, hunger, or any number of other imagination-enhancing elements. It's fantasy, not scientific theory. There is no empirical evidence for it, and no, the Bible does not count as empirical evidence for anything except the existence of the Bible.
Strictly speaking, even evolution is not really "a theory." Evolution, the change over time observed in Earth's living organisms, is the fact that Darwin's theory of natural selection was developed to explain.
It's very difficult to get this idea of what it means to be a scientific, as opposed to a folk, theory across to people. This past summer semester I had one student who got all the way through an introduction to cultural anthropology only to write, in his final essay:
The Big Bang Theory, evolution, and many other theories are just that, theories.He retained the folk definition of theory to the end, despite the time spent explaining that theory in science does not refer to a casual, unsupported guess. I'm not prepared to state categorically that religion makes you stupid, but there is some empirical evidence for that hypothesis, and it is falsifiable.
