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.
“Could have been six 24-hour days, or it could have been 6 1-million year eras.”
Perhaps, if we didn’t have contextual clues to settle the matter, it could be a “grey area”, however, the text is quite plain, when it says, for each day of creation, that there was evening, then morning, then the next day. If you want to ignore that and believe it is talking about ages, then you are not trying to interpret what the text says, you are trying to fit the text to what you want it to say.
