The fourth argument poses a theological problem, rather than a scientific one.  It poses the idea that God created the universe mature, as creationists believe he did with Adam in Genesis.  With respect to light, it means that the light would have been created in transit, or already on its way to Earth, with no alteration of it’s speed.  Unfortunately, this argument is immune to scientific inquiry, however, we can still examine it using SN1987A.  Anything we’d see from beyond 6000 light years would be artificially created light, rather from the objects themselves.  It would imply that the supernova explosion had already happened before the universe came into existence, meaning, it didn’t happen at all.  Answers in Genesis recognizes this problem: “It would mean that these exploding stars never exploded or existed.  God merely painted pictures of these fictional events.  It seems uncharacteristic of God to make illusions like this.  God made our eyes to accurately probe the real universe; so we can trust that events that we see in space really happened.  For this reason, most creation scientists believe that light created in-transit is not the best way to respond to the distant starlight problem.”  The argument is painfully too similar to the claim that God put ancient fossils here to test our faith.
