For the record, I don't know much about chronolgy. But, like a good detective, I would wonder about "motive." What would be the motive of a person in 1906 (or later) to want to tamper with the evidence? All the tablets and cylinders point to 587/586 BCE as the time of the destruction of Jerusalem, thus according to secular chronology. Even the WTS admits that. However, if someone were to tamper with a tablet to point to another date, e.g., 607 BCE, then I would become suspicious. It would be out of sync, the only tablet to do so.
I understand the argument of the seventy year desolation. Quite a few scriptures indicate 70 years. Counting back from 538 BCE, specifically 539 BCE (the release of the Jews by Cyrus), would bring one to 606/607 BCE. Only problem with that view is that it is supported by Bible writers only, and perhaps Josephus. All secular evidence points to 587/586. Perhaps Furuli should stick to this argument, rather than taking on secular scholars or their sources.
