Genesis chapter 1 tells us that God created the sun on the 4th Day of Creation week and the chronology of the Bible puts that about 6 thousand years ago.
The sun is at a distance of about 150 million km and that means light travelling at about 300,000 km/s would take about 8.3 minutes to travel from the surface–the photosphere–to Earth.
But doesn’t the very existence of the sun present a problem for biblical creation? The idea is that the sun is no more than 6 thousand years old. Then how does light reach Earth in that short period of time?
No problem you say! It only takes 8.3 minutes to get to Earth so it easily fits into the 24-hour period of the Creation Day 4. And certainly into the 6 thousand years that have passed since Creation. You say there is no problem there.
In relation to the stars and galaxies, millions and billions of light-years distant, it is admitted by biblical creationists that there is a problem–a starlight travel-time problem–which some have suggested potential solutions for.
My current view is that the ASC model is by far the simplest solution to that problem (see list below).
