Scientists tell us that the light from most stars that we see either with the naked eye or telescopes is in excess of 6,000 light years. This would imply that the stars are more than 6,000 years old. Indeed, super-nova star explosions have been observed at these great distances. How can this be if the universe is less than 6,000 years old?
1. The scientists are wrong. Stars are actually quite close to the Earth. They are embedded in a rigid substrate known as aether. The aether revolves around the Earth about once a day. You see, this whole problem started with those chaps Galileo, Kepler, and Copernicus and they were just a bunch of heretics. Just stick with the model of the geocentric Earth and you won't have any problems.
2. God created light that looks like star light, yet did not originate from the stars. Consider that God created a fully functional universe for the benefit of Adam and mankind. When Adam appeared on day six, certainly his night vision included a full spectrum of star light, yet our closest star is 4 light years distant. This full spectrum would include the occasional super nova star burst explosion, despite the fact that the stars never actually existed.
3. During the six days of creations, the star light exceeded "c", or the speed of light as we know it in the present day. The laws of nature were not set in place until after these primordial days of creation. Dr. Ostroff expands on this idea in this analysis: http://www.toriah.org/science/big-bang/big-bang.pdf
4. We don't know. Nonetheless, this doesn't bother us. There are many wonders of the natural world that defy explanation and this is yet another example.
