“Time dilation also results, but not due to a net gravitational effect in a finite bounded universe—it is due to the enormous stretching of the fabric of space. Space is not nothing—there is a lot of energy in the vacuum and, at Creation, God caused space to rapidly expand such that clocks on Earth at the centre of the expansion ran very slowly compared to clocks in galaxies in the expanding cosmos.”
Perhaps you should research gravitational time dilation a little further before you start poking fun at it. You will probably have an easier time digesting GTD if you read about it from a Temple of Darwin approved source:

At a rapidly slowing speed at first. I'm not really sure on where we are in this universe though. The middle, somewhere near the edge? Somewhere in between? We really have no way of knowing. Our sense of "time" and a "day" didn't really begin until creation of the sun in our solar system on the third(?) day however. And our biblical age isn't necessary the age of the earth. The biblical age starts with the creation of Adam, so the biblical age is really just the age of mankind. We really have no idea how long a "day" was on the first (day1)of creation, and the bible does word those first "days" differently. Now a "day" is in relation to one rotation of the earth using our sun as a reference piont.
