Exodus 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.

So, how did the light get to earth since the stars are billions of light years away? Light would take billions of years to get to earth. Sounds like a good argument, but it is not. Every old-Earth, old-Universe, and Molecules-To-Man evolution story is simply a fabrication based on arbitrary and false assumptions coupled with wild rationalizations that have been repeated so often that some people have become brainwashed. In fact, big bang people find that the math doesn't work for their Naturalistic Secular Humanist religion theories. They can't come up with a way that they can make the math work other than creating make-believe types of things that no one can see or test or detect, like dark matter. "Well, dark matter must exist because my math doesn't work to support my anti-God theology." Also, be sure to study this Indepth Study of Distant Starlight.

The fact is that there are several theories, based on real science, where God could have used existing observed phenomenon without miraculous intervention. Of course, making everything from nothing was obviously miraculous. God created time. He lives outside of time in eternity. He is not regulated by time. He could cause time to move at different speeds in various parts of the universe. If that were the case, then the distant starlight problem is solved.

Bottom line, we don't know. He didn't tell us. He has not yet revealed it. Yet the Secular Humanist version is far less scientifically defensible than is the version we find in the Bible.
