The usual creationist dodge is that God created light on the way to the Earth to make it look as though the object was very old. In this case, God faked a supernova explosion of a star that never existed.
Which is a remarkably cynical ploy for anyone claiming to be a Christian.
There's a more imaginative and honest way around this reality:
Aardsma & the Virtual History Hypothesis
Young-cosmos creationist, Aardsma (Ph.D. in nuclear physics from the University of Toronto) believes that his “virtual history” hypothesis is less problematic than the usual creationist excuse of “creation with apparent age.” Aardsma even admits at one point below that “I think there is enormous evidence of biological evolution (meaning extensive changes to flora and fauna)—-again, in virtual history.” But not in real history. Read his explanation of virtual history below and see if you are convinced:
“The two ideas share some similarity, but differ at a basic level both philosophically and theologically. Creation with Appearance of Age gives the impression that God arbitrarily painted a facade of age over the creation — that He could have chosen to leave everything looking its ‘real’ created age (i.e., roughly 7000 years, by my best Bible chronology reckoning) if He had wanted to, but He chose instead to make things look much older. This immediately raises theological objections: ‘But why would God do such a thing? Isnʼt it fundamentally dishonest to make something look like it isnʼt? Isnʼt God being deceitful?’” (This is where the “heresy” mentioned above comes from.)
“The virtual history view never encounters this problem. It says that the people who are saying ‘creation with appearance of age’ donʼt understand properly what the word/idea ‘creation’ means. The virtual history view goes to the analogy of human creations to try to show what ‘creation’ means. It takes the creation of a story by a human author as (probably its best) analogy. It observes that in all such stories one always has a virtual history present—-grown characters wearing sewn garments and living in already built houses… right from page one of the story. What is implied from page one of the story is a cause-and-effect virtual history to the story, stretching back into the indefinite past. This virtual history in no way contradicts the actual date (in the story charactersʼ time) of creation of the story. (That ‘date’ we would fix at page one of the book, since that is when, in the story frame of reference, the story world comes into existence.) We find by such analogies that an ‘appearance of age’ is inherent in what ‘creation’ means.” (This is where the “redundancy” mentioned above comes from.)
“But this ‘appearance of age’ is not an add-on and is not arbitrary. Try to imagine writing a story which does not have an ‘appearance of age’. After you have completed that exercise, try to imagine writing a fiction story which has a false ‘appearance of age’. I find that it is intrinsically impossible to create such stories. I.e., you cannot have a ‘creation with an appearance of age’ if you mean by that anything other than a creation with its inherent virtual history. To ask for a creation with a false appearance of age (which includes the case of a creation having no appearance of age), is to ask for the impossible/ridiculous.” (This is where the ‘absurdity’ mentioned above comes from.)
“We are living in a ‘story’ God created. God is both author and reader of this story (e.g., ‘For in Him we both live and move and have our being.’ Acts 17:28.) (Note how this works. A story-world has no existence in the book; its existence is in the mind of the author and readers.) Page one opens about 7000 years ago our time, (the only time frame we have access to). This ‘story’ has a virtual history stretching back billions of years. We find this to be the case by computing the time it would take light to travel from remote galaxies we see in the sky, or by computing the time it would take radioactive elements, such as uranium dug from the earth in natural ores, to decay as much as they have. These great ages in no way negate the fact that page one opens 7000 years ago. Nor does our virtual history, with all its dinosaurs etc. negate the fact that we are created."
It sounds loony, but it has the obvious virtue of not assuming a dishonest creator, which is what "appearance of age" requires.
