Good post. The question should be how old was the universe when God created it? When He created the Earth how old was it? When He created trees how old were they? When He created Adam how old was he? When He created Eve how old was she?
This throws all dating out the window. It becomes a mute point. So maybe He did create everything 7,000 years ago and made it all in it's proper time.
God does not have an age. He is before and He is present and He is after. I do agree that dating is not so important, especially if you keep in mind that He Is (I Am).
