As Jeremy Wiles explained, we could not possibly know that the earth is billions of years old because Noah's flood would have washed away all the evidence. Thus, the reason that Robertson is making this claim, Wiles asserted, is because "he doesn't want to feel like an outcast" and is trying to make the Bible fit in with the secular scientific worldview.
But that is a losing strategy, he explained, because history has always shown that the Bible is one hundred percent scientifically accurate, which is why Christians have always known that the earth is round while it was the scientists who believed that the world was flat:
Jeremy Wiles: I think Pat is trying to fit the Bible into modern scientific thinking. I really think that he feels the pressure from the scientific community, not so much because there's evidence to support billions of years but rather because he wants to conform to the idea so that he can have a more acceptable worldview. He doesn't want to feel like an outcast, but history has shown the Bible is scientifically accurate time and again.
Scientists once thought the world was flat. Columbus faced opposition in his attempt to find a western route to Asia because people thought the earth was flat. But the Bible told us He sits enthroned above the circle of the earth. The Bible is teaching us the earth is a globe, it was round, it was a circle, a sphere.
Rick Wiles: And I think about Obama, when he wants to mock Christians or conservatives, he'll refer to them as the Flat Earth Society. But the Christians were not the ones who were saying the earth was flat, it was the scientists. The Christians knew the earth was round because they read the Bible and they believed the Bible.
For the record, the idea that most people believed the earth to be flat is a myth as "no educated person in the history of Western Civilization from the third century B.C. onward believed that the earth was flat."
