Huh?! Have you totally lost the plot? Your claim isn’t at all supported by ‘my reasoning’. The opening words of Daniel identity a setting, but there’s nothing about the statement that confirms when it was actually written. You don’t understand that a later writer could have access to historical details of an earlier period? What is wrong with you?

The opening words of Daniel sets the historical setting for the book which along with the other dates given are of historical events not in the 2nd century but in the sixth century.
There is not a single shred of evidence that Daniel was written in the 2nd century BC but is simply a theory cleverly designed to discredit prophecy. The six datable events anchor the entire book in the 6th century BC for any other claim is simply nonsense.
