God created light 3 days before creating the sun.
True, but is that really relevant to the OP's question? When we say that the sun is second/third generation we mean that the sun was formed from material from two generations of stars that lived and died before our sun was ever formed.
YECism, in general, is an exercise in jamming huge amounts of process into very short periods of time.
The point I was shooting for, was that the evidence for "two generations of stars that lived and died before our sun was ever formed" could be YEC interpreted as evidence for what happened during the creation process of day 1. And it could be a pre-sun light source, although even that wouldn't explain the pre-sun days and nights.
More evidence for something that didn't happen (a young universe/Earth creation).
