The whole thing falls down with one simple fact proved beyond doubt...
The destruction of Jerusalem by Babylon was NOT in 607 BCE.
The very fact the WT used to teach it was 606 BCE until they realized that there was no zero year in between 1 BCE and 1 CE shows it is made up because they changed the start date of their prophecy, something set in stone in the past and documented by thousands of sources compared to changing the end date of their prophecy...something invisible.
We can all go into the crux of it but there is zero evidence anywhere that 607 BCE was the year Jerusalem was destroyed.
