‘scholar’:
Nope The following factors mitigate against the Return of the Exiles in 538 BCE;1. Chronology of Darius the Mede
2.. Timing of the Decree ?
3. Proclamation of the Decree throughout Empire
4. Preparations by the Exiles prior to their Journey
5. Return trip home- route and time of Journey?
6. Resettlement home in their cities ?
7.. Timing of Altar Inauguration - Cyrus. 1st to 2nd year?
8. Calendrical reckoning used by Ezra?
Thus, any chronology for the Return must fully account for these factors and shows that to cram all of these in one year - 538 BCE is impossible but the following year- 537 BCE makes the impossible now possible and highly probable.
None of these are legitimate problems. But rather than deal with them yet again on this forum, let’s spare a thought for the fact that the claim that it’s ‘impossible’ is coming from someone who thinks every animal species in the world survived a magical flood by spending a year in a wooden box. 😂
