Ok.

We're always looking toward the center, i.e the BB. Moreover, all galaxies were formed after the BB.
Does that answer your question?
This i what you see...
But could it be possible that it is only a naive interpretation ?
When i look into the fog, things tend to disapear.
Are things disappearing really and tend to disappear much an much they are far from the observer ?
No, and you know that because you can go there where things are supposed to have disappeared, in the fog, and you can see that they are there without change.
Same in the universe.
What you call the BB, the "beginning" could be like in the fog, the limit where an object disappear due to the distance.
But there, where you think there is no galaxy (because you suppose they were not yet created), there are galaxys, the same as the all the other you have in your surrounding.
Not convinced ?
To verify this, if you could... you can travel like the light, and for the light the time of the travel is equal to 0 seconds (so yes i know you can not take a photon as reference, it has no sens and blablablabla, so suppose you travel just a bit under the speed of light and you are very small).
So, what is there, "for the light", at 13.8 Gyear distance ? Some galaxys or some proton soup ?
Some galaxys ...
Strange world ?
No, its like the fog.
The trick, in my opinion, is that, because of the expansion, at 13.8 Gyear distance, the expansion speed is around the speed of light.
So you know what happen if something go away from you at the speed of light : It looks freezed.
But there is something else you probably dont know : If a material object go away from you and attain relativist speed, it appears like if he was broken, and if he attain almost speed of light, he appear like he would be "exploded" (but he is not) and we observe the things that constitute the object, like atomes and even more tiny parts.
This is what you see at the 13.8 GYear limite, galaxys that look like they are exploded, but they are not.
This can be verified i think because there should be some signature of this phenomenom in the WMAP observation.
