What a nice little list you have presented. So is one to now surmise that scholarship is now saying that 538 BCE is the official date for the Return. Can now from this list have it positively established that 538 BCE is the precise date. If this is the case then why is it not the case that such research has not yet appeared in the scholarly literature? All that you have done is simply cherry picked or someone else a fearsome poster has provided you this information. In order to impress scholar you must quote much better sources, sources that simply dont give a date but explain why a date is selected above and beyoud other dates.
