Hype only carries you so far, and the amusement park is not some one-shot deal; it must continue to make money over time. The Creation Museum will have a greater impact than early hype; if it's doing well he can get more interest in his new venture. By its fifth year it was already just above break-even. No idea if it has reversed that trend in the past 2-3 years.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
