At its core, creationism is really a political movement. It trades knowledge and science for popular influence. In the world of the creationist, all is relative to social standing, ergo they think that they must be the ones at the top of the totem pole. To do that, it is necessary for them to eclipse science. Delude themselves as they might, it's not about God to them at all. It's just straight up jockeying for power.
