OTOH, a cubit isn't a real accurate unit of measure. It's the length of the forearm from the elbow to the tip of the middle finger; generally held to be about 18 inches. The supposed inaccuracy can be accounted for by simple rounding, which is used in our lives daily. If someone really wants to look for reasons to reject the Bible as being unreliable because of "inaccuracies" I suppose that one can find anything. We still say the sun rises and sets. We know it doesn't but everyone says it and no one is accused of lying. But it's generally just excuses to reject religion.
Yes, and I've heard that the ancient Hebrews were really counting months instead of years when they passed on the ages of the patriarchs as well.
It just reinforces that the Bible cannot be counted on to answer questions of specific fact, especially in such things as the age of the earth.
I don't expect to convince devoted fundamentalists that the Bible is not the inspired word of God. I am trying to show that the Bible is not literal fact. Unfortunately, people who have invested their lives in this belief system will almost always find a way to rationalize any discrepancies. It is far easier to do this than to change the basis of their belief structure.
This unwillingness to change in the face of evidence is a fundamental part of human nature that has been demonstrated over and over throughout history.
Only severe, life changing crises have been shown to be capable of initiating a serious change in belief structures. Those that can be persuaded by evidence are a small minority.
