Tom,
There are many ways to show the error of the "Framework Theory" and those like it, e.g., that which Poythress espouses but putting it to the test; a basic approach to those who hold to a presuppositional apologetic defense of the faith.
Here's just one way which I find very effective. Let's look at a portion of Scripture which I have previously mentioned, Exodus 20:8-11
Exodus 20:8-11 (ASV) "Remember the sabbath day, to keep it holy. Six days shalt thou labor, and do all thy work; but the seventh day is a sabbath unto Jehovah thy God: [in it] thou shalt not do any work, thou, nor thy son, nor thy daughter, thy man-servant, nor thy maid-servant, nor thy cattle, nor thy stranger that is within thy gates: for in six days Jehovah made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore Jehovah blessed the sabbath day, and hallowed it."
Now, let's substitute the word "day"
yom with the word "era" which those who reject the word "day" to mean a 24-hour period of time. This is how the Fourth Commandment would read and thus allegedly be understood by the Israelites:
Remember the sabbath era, to keep it holy. Six eras shalt thou labor, and do all thy work; but the seventh era is a sabbath unto Jehovah thy God: [in it] thou shalt not do any work, thou, nor thy son, nor thy daughter, thy man-servant, nor thy maid-servant, nor thy cattle, nor thy stranger that is within thy gates: for in six eras Jehovah made heaven and earth, the sea, and all that in them is, and rested the seventh era: wherefore Jehovah blessed the sabbath era, and hallowed it.
Among the several problems which can now be clearly seen, the most blatant is that one is not to do any work, nor are any of the man's family, not his servants nor his servants nor even a visitor in his house for the entire
era. Now, if this "era" is to be understood to be a period of time consisting of several million years or even 100,000 years, then this poses an insurmountable problem.

Are we to seriously believe that the Israelites understood "day" to actually be "era"? Then if so, why did they violate this commandment during their entire history? And more so, assuming that this commandment is applicable today, which I do of course, then are we to abstain from all manner of work until....?????????? perhaps Christ returns?

OR, are we to arbitrarily change the meaning of "day" in Exodus 20 to mean a 24-hour period of time? If so, by what warrant are we to understand that Moses used "day" in these two places differently?
Personally, I find it much easier to explain that the "day" in Genesis 1 & 2 and also in Exodus 20 are 24-hour periods and that God created a mature earth upon which man to dwell.
