How the Book of Genesis showcases progressive revelation

The enlightenment brought progress to Western Civilization. Humanism, Historicism and Realism in Western, European traditions, gave way to Modernism and then Postmodernism. Along the way, the primacy of one of Western Civilization's foundational documents, the Bible, was eroded and supplanted, to the point that it is not only ridiculed as irrelevant, and a source of ignorance, but even considered dangerous. Are these viewpoints valid, or does the Bible still have important relevance and even undiscovered truths that can help guide humanity's path forward?
