1. The Anisotropic Synchrony Convention
In Special Relativity, space, time, and motion are all relative to the observer, and not absolute. Hence one cannot synchronize distant clocks in an objective, absolute manner satisfying all observers.
Based on the distance to the sun and the canonical speed of light, c, the light travel time from the sun to Earth is about 8.3 minutes. But, and here’s the problem, it has been suggested that light from the core of the sun takes about 170,000 years to reach the surface. This is because gamma photons, generated in the thermonuclear fusion reaction at the sun centre, undergo a random walk as they are absorbed and re-emitted by nuclei on their way to the surface...
There is only one biblical creationist cosmogony that I know which can explain it, and it does it easily. It is Jason Lisle’s ASC model. That ASC model says that the physics of Einstein allows us to time events as in the Days of Creation, 1, 2, 3, 4, 5, etc. And we time those events by when an Earth observer could see the events happening.2 Thus when the light from the sun first arrived at the Earth it was Day 4. It does not matter, it is even irrelevant, how long the light took to travel...This is the language of the Bible. Events occur when they are observed. The sun was first seen by Earth observers on Day 4 and that defines when the sun was created. That event occurred 3 days after God created the Earth on Day 1 about 6 thousand years ago.
