If God created the universe less than 10,000 years ago, we would not be able to see stars because the light would not reach us until the very distant future.
That is, of course, unless he created the universe with light beams billions of light years away already reaching the Earth. Creating a new universe to appear old seems a bit disingenuous to me. as well as extremely inefficient and time-consuming. God can do anything, so why go through all that trouble simply to give us some light at night? And then cover up the light quite often with cloudy weather? Why not create a light-source in the atmosphere? Why create darkness? Or the need for light? Think of the stupefying size and mass of the universe! Creating a universe with all that unused energy and matter, a universe that is 14 billion light years across, just to give us some nice stars to look at seems a bit overkill.
The point here is to stress a more critical reading of the Bible, rather than simply glancing over “Let there be lights in the vault of the sky to separate the day from the night,” take it at face value, and move on. Now that we know so much about the universe, one needs to start questioning the validity of Biblical accounts regarding Earth and space.
