As is the case with most theological revelations, you begin with what you observe and you go to the Bible for instruction concerning what you observe.
In the case of historical record, you can make no observations. You cannot observe the administrations of Abraham Lincoln, George Washington, King James, or Caesar Augustus. There is no observation to be made, only something you're told. So also in the life of Christ. You cannot observe His birth, death or resurrection. You cannot observe any of His acts or those of His Apostles. You are only told, and you either trust what you're told, or you don't.
That is how one approaches the Creation Week narrative.
Now we can hash the reliability of the witnesses, and we can make the case that the witnesses are trustworthy, but that doesn't change the fact that contrary to your presupposition, in most cases, and especially in those which are most critical, revelation comes through the verbal testimony of a witness. It is your only source of knowledge for the life and teachings of Christ.
We observe stars in the night sky that no longer exist. It takes light billions of years to reach us from those stars.
Assuming certain things, yes, but our observations and knowledge are incomplete and there are a host of assumptions that accompany them, and from which one leaps to dubious conclusions. It's like measuring the present erosion rate of the Colorado River and assuming that tiny force and path were constant and then making the assumption that the river is what cut the Grand Canyon in the first place.
We observe that the universe is expanding at a particular rate which means it is very old.
Assuming the rate of expansion has been constant, and that is a big assumption based on no science whatever. But there's more. All the galaxies are observed to be moving away from the earth and each other at the same rate. Assuming the earth is at the center (or very very near the center) of the universe, that observation is easily explained, and in no way counters a young earth cosmology. But if one feels the need to remove any hint of purpose in a creation, he can just as easily assume a cosmology with no boundary or center (and that does not mean an infinitely large universe) and explain the observations. An unbounded universe is the prevailing "scientific" opinion.
One cannot prove a bounded or unbounded universe, but both will explain the observations. The only difference is the assumption, not the science.
And then, because of the TRADITION taught us, not because of what the Scripture actually SAYS, we say, "Oh God, how can these things be?" Then divine Providence points us back to these Scriptures and we see that "day" means "epoch of time" in the Bible more often than it means 24 hour period.
Actually, what God will do is teach you that your eyes are dim, your observations are incomplete and your brain is small, and that you are a presumptuous clod to base your hermeneutic not on His text, but on fragmented, incomplete data and arbitrary assumptions.
Here's what it boils down to. Rick has not measured the speed of light. He has not observed the expansion of the universe. Hell, he's not even well-read on the subject. He just trusts what he's been told assuming that he has been told the whole story, and the rest is the fruit of his immersion in a culture based on Darwinism. That's why I can say with certainty, the reason anything in creation looks old to him is because of his conditioning.
