How can a calculated precise date of 607 BCE be wrong when you cannot agree as to whether it is 587 or 586 BCE for the Fall of Jerusalem? How can it be that a definite date-607 BCE be falsified by an indefinite date-586 or 587 BCE?
The logic here... 🤦
You know the difference between precision and accuracy, right?
I can give you an incredibly precise measurement for the weight of a full grown elephant: 5.1745385637655364469346 ounces. Is it accurate?
Accepting for a moment that there a big debate between 586 and 587: The fact that you propose a more precise date doesn't mean it's correct. And if there is a large body of evidence pointing to a less precise date range, it can most certainly disprove your incredibly precise fantasy date.
