But you don't have to believe in the literal Christian creation story 7000 years ago. Most lines of Christian thought allowed for non-literal accounts as far back as the first century A.D.
The Hebrew term "Yom" translated "day" is mentioned before the sun and moon.
Also, there's an unspecified amount of time between Genesis 1:1, when "God created the heavens and the earth" and 1:2, which says "But the earth became waste and emptiness."
These two clues tell me the text is not meant to offer any information about dates and times.
