So what does it all mean.?
That God didnt need long ages or a day?....could have done it in no time at all?
OK, since Gluadys isn't here I will give it a shot. She may be able to explain it better than I could.
You have to think of the text not as a literal historical narrative, but a figurative, symbolic and typological account. It is using a poetic structure, not meaning to literally describe the exact timing or process at all. It was meant to convey the great concepts of God's creative work in a very evocative and powerful format. It is not at all that it is untrue, or false in any way, it is just written in a style that was common at the time, but very different than we prefer today.
We like our history, in this modern age, to tell about the past using a literal chronological and factually narrative style. We like marching through the facts one after the other. But the ancient cultures in the near east would never consider using such a mundane and prosaic style for describing the most momentous and mind-blowing event in history. Something so big we could not possibly understand what actually happened. It would be like writing Song of Solomon as a clinical account of the chemical and neurological processes of physical attraction.
So, we accept that when the author was using the term "day", he was using it in the typical sense of a 24 hour period (or, more correctly, a 12 hour period, but that is besides the point). BUT, and here is the key, the author was not actually wanting us to read it as God creating in six literal 24 hour periods.
Here is my "tree" example. It is not the best, but I think it works. Let's say there is a poet who wants to write a poem about a family history, but wants to use a tree as a symbol for that family. He will never mention that this is some symbolic representation, he just expects the reader to get it. So, when he is using the word "tree", he IS using it in the "leaf and branch" meaning of the word, rather than, say, the computer file system meaning of the word. And, he wants you to visualize a literal, leaf and branch tree. BUT, he is not actually writing about a tree, but a family, and he expects you to get that.
Similarly, the writer of Genesis 1 is using "day" in its most common sense, and not an "age" sense, etc. And he does want you to visualize a regular day when reading his poetic account. BUT, he is not actually writing about a series of days, and expects you to get that. But we have a harder time with this today, with our modern minds.
Augustine, for example, got it, and thought that God created in an instant, and just allowed it to be written using the "day" motif as an accommodation to humans limited understanding and need for such a structured presentation.
