Except what I've said is entirely relevant to this topic. Imagine, for a rough example, that you encountered a species of animal that you determined upon years of investigation grew exactly an inch every year it has been alive since its birth, with no varying rate. Now imagine that you knew it's ancestor (you had encountered it with it's mother, for example) but knew nothing about the origins of this ancestor to extrapolate the life span or history of this creature before it had died. Being left with only the offspring, you measure it to be 300 inches in length. From this measurement, you infer that the creature must therefore be 300 years old. The problem with this reasoning is that you would have to assume the animal was less than or approximately an inch upon its birth. For all you would know when the animal was born it could have already been several feet long, so that your measurement is highly inaccurate based on this presupposition.
My point is, we have a considerable potentiality as inferred from the Scriptures that the universe was created a comparatively short time ago, with an explicit indication of its mature initial conditions as explained in the 6 consecutive day creation (which must be repeated in case you want to erroneously call this "lying" which requires that you not be provided the information explaining the appearance of age, which we would be by this simpler, more obvious interpretation). If this is the case, then even if the universe is young it will still appear old with the presupposition that extrapolates into the past the accumulation of all matter and energy into its finest potential point. It could more aptly (but still incorrectly) be called lying to say that God made the universe over a long progressive period then oddly described it as six consecutive days divided by evening and morning.
