The Solar system swinging by the pair in the middle of the intro dialogue is not to scale. (Otherwise it could not fit on any screen or would be too small to see.)
The views of the universe shown at the beginning (for example, the 'Pillars of Creation' in the Eagle Nebula), are as they would be seen looking from the surface of the Earth (or at least close by), and as it would appear in the present day.
This implies that, since its creation, everything in the universe has always looked that way and looks the same as we see it, no matter where you are in the universe. (Even the orientation of the Pillars is the same as is commonly depicted or shown in photographs taken from near Earth).

Crowley asks Aziraphale, "Why don't you put Earth in the middle of the universe so the view's better?"
However, Crowley should know that the universe has no "middle" (after all, he created it). The universe is three-dimensional and it is expanding into four-dimensional space (much like the 2D surface of a balloon expanding in three dimensions; from the perspective of anything on the surface of the balloon there is no centre).
