AIG and the Creation Museum are managed by really genuine (and talented) people. I've known a couple of the people there many years before there was talk about a museum; their private faithfulness towards scritpure was always solid, and in public their testimony and character towards other people was equally solid. This is not a business to these men...it's a calling!
I haven't seen their particular Ape-man exhibit, but I have seen an exhibit on Lucy the Australopithecus at the Field Museum in Chicago. Honestly, I wished I had my children with me, because the exhibit was a great example of how to design a sensory experience to provoke not only imaginations, but also emotions. There was as much imagineering and religous sanctity in that exhibit as any I've seen at the Creation Museum. The low awe-inspiring spot lights on the bone fragments, the hushed quietness visitors were encouraged to show as they approached the holy relics, and the artists rendering of the flesh and blood form of our supposed noble ancestor...it was all very moving!
Now I know more and more Christians these days are disowning a literal 6 day creation, but one thing I've noticed about young earth creationists...because they don't comprimise their beliefs about Genesis, they don't comprimise their beliefs elsewhere in scripture either.
Which is why I agree with Hulsey about their bookstore...it's not often you find Puritan and Spurgeon books next to geology and astronomy books!
