Take in mind the original word for "day" in our English Bibles is the word "Yom" in Hebrew - the word Yom not only means day, but season, era, year, aeon, etc. That's a translation thing, where we perceive it literally. While it could have happened in day, it could alsooo have happened in a season, or a year, or a season of multiple years - or in an instance. It doesn't really affect our faith that's in Jesus Christ and not in the earths age, soooo *shrugs* do what you will with that tidbit
