Psalm 19 – Skeptic's Annotated Bible answered

According to the author of the SAB it is unscientific to say we see God's handiwork in the heavens. We must put our blinkers on to do science. How can science, which excludes God beforehand, be called science, if God existed? If God existed, such science would come to severely twisted answers. It reminds me of the novel “Permutation City” by Greg Egan. In this novel we find a description of the Autoverse universe. The beings in this universe are artificial, created by humans. But when their scientific endeavors led them to a theory that accounts for their existence but excludes being created by an outside force, the humans attempt to make contact with them.
That story has some similarities to scientists in our day trying to account for creation without a creator. But thanks to creation research, we can take this verse even more literal than had been thought. Some people believe that the light of the stars that are millions of light years away and reaches us, has been created in transit so to speak. If light of a supernova that happened millions of years ago reaches us, that event did never happen. But with our latest understanding of the universe and that time can run at different speeds from here on earth, the best creation researchers believe that God is not showing us events that did not happen. When we see a supernova, we see light from an event that did happen. When we look back in time with our telescopes, we can actually look back, perhaps even to the fourth day of creation. We see God creating the stars. When God created the stars, he also stretched out the universe, causing time to be greatly accelerated. So we literally see the handywork of God.

Yes sure, David is giving here a physics class. If every poet that uses language that describes the sun in anything less than Einstein equations is accused of believing that the sun rotates around the earth, we're in for a great purge.
