Jwdeepthinker , I think you’ve been ready someone’s work that’s jumping over hoops to make his ideas work. First off there’s no record of any Darius the Mede. The book of Daniel is the only mention of this guy and it’s a 2 nd century BC writting where the writer doesn’t know his history. Darius was a Persian and the writer even mentions his lineage but he even gets that wrong. Darius the Persian comes later in history.
Another thing to mention is the Bible said Tyre would never be rebuilt yet it was no only still around for Alexander the Great to destroy it but after he allowed it to be rebuilt.
