Another popular idea is that light was created in transit. Even though the star is further away than 6000 light years, the light traveled a shorter distance since it originated at a distance appropriate to reach the earth at the right time.
This, of course, would have some rather silly consequences.
Consider for instance the 1987A Supernova, more than 150,000 light years away (if I remember it correctly). If light was indeed created in transit some 6000 years ago, it would mean that God created light in transit showing us events (for instance this supernova) that have never actually happened.
So if someone wanted to use this in defense of your 6000 light years large sphere argument (the stars aren't actually within the spheres, light was simply created in transit) they'd still have some 'splainin' to do.
