WTS has no proof for 607 so they try to discredit the proof that there is not enough evidence found to support 586/7 date. The fact is there is more proof to support Neo Babylonian reigns with proper years than for 539BC as the date of Cyrus capturing babylon. Carl Olof Jonnson's Gentile Times Reconsidered is an excellent book with tons of material showing why 607 fails the history test. One of the biggest facts proving beyond a doubt are the artifacts which include the lunar eclipses and the year of the king's rule since the detailed description of the lunar eclipses can not have taken place 20 years earlier. There are many many of these artifacts from various years and various lunar eclipses from different Neo Babylonian kings in power which could not have been all changed by Persians nor a conspiracy to hide the 20 years that wts imagines.
WTS' pillar has no foundtion since 607 is false, 1914 means nothing, and thus FDS weren't chosen in 1919 thus WTS is a fraud.
