That article is ridiculous. Materialism didn’t tell us that God created the heavens and the earth in six days, the BIBLE did. If anything, materialism is responsible for the idea that we must reduce those passages of the Bible to “poetry” or “allegory”, in order not to run afoul of materialism. That is certainly not the traditional, historical Christian interpretation of the passages.
Could have been six 24-hour days, or it could have been 6 1-million year eras. To me, it doesn't matter either way. Nature is filled with examples that point to an intelligent designer (ice is less dense than water, carbon-based life, the consistency of form from atoms to galaxies to name just a few simple examples), and more to the point, matter does not and cannot create itself. No matter how He chose to do it, God was clearly at the helm of creation. Anyone who claims that a watch can exist without a watchmaker is a liar or an ignoramus. In the long run, it takes a great deal more FAITH to believe in a universe without an intelligent creator, than to believe in one God created.
