A recent topic about whether the Watchtower view of 607 BCE is SCRIPTURALLY supported is linked below. This new topic should provide a better place to discuss the SECULAR evidence. I also think it would be useful to discuss the methodology that the Watch Tower Society has historically used to treat this evidence.
I would hope that we can do this without so much side discussions of unrelated topics. To avoid another topic that goes on for 30+ pages where only half of them were on-topic, I would suggest that if we get enough off-topic posts, we merely move them to another more appropriate topic.
