It appears that there is light arriving here that originated millions ... or even billions ... of years ago. If this is so, then all Young Universe Creationists are in error.
I prefer to discuss the astronomical discrepancies between the standard scientific view and that of the Young Earth Creationists because it is less emotionally charged.
A case, albeit a poor one IMHO, can be made that a belief in evolution necessarily leads one to lose a sense of the special dignity of Mankind and our relationship to our Creator. However, I can't see how one can make any case ... however poorly thought out ... that believing that supernovae are indeed billions of light-years away from Earth leads to the same sense of loss.
It would seem that we at FR that share so many opinions in common could come to a consensus on why it appears that light is just now arriving on earth that seemingly originated billions of years ago. Is it because:
1. It was actually generated billions of years ago as most astronomers believe.
2. It was created only about 6,000 years ago, but in such a way that it appears to be billions of years old. (See Omphalos hypothesis)
3. There are some errors in our assumptions or calculations. Maybe the velocity of light has changed over the millenia as some have suggested. (See Starlight Problem or c-decay)
If we can't all come to some sort of consensus with regard to the astronomical data, then it seems that reaching a consensus on the geological or biological data is entirely hopeless.
If the YEC community were to come to a consensus that a 13.5 billion year old universe is not counter to anything written in Genesis, then maybe it might make some sense to start focusing on biological evolution. But until such time, the YEC community needs to make a better case for how the data we have been gathering for hundreds of years jibes with a ~6,000 year universe.
