There being multiple 'seventy years' is impossible for this only confuses the subjects and using other dates such as 605 BCE or 609 BCE are also impossible for the beginning of the period is also impossible. Further, the ending of the period in 539 BCE is also sadly impossible.
Actually, you are very mistaken. Jeremiah 25:11b,12a states: "[T]hese nations will have to serve the king of Babylon seventy years. And it must occur that when seventy years have been fulfilled I shall call to account against the king of Babylon... " As the nations ceased their servitude in 539, the ending of the period in 539 B.C.E. is not only NOT "impossible" -- it is necessary.
