The textual and editorial history of the "bible" is fascinating and I encourage everyone to delve into it, at least a little.
Here are some, err, facts.
No one knows who wrote the book of Daniel.
It is impossible to determine the degree of historical accuracy of that text.
We do not have the "original" manuscript (as is the case with all the books). What we have in this case is cobbled together from later copies/translations written in Hebrew and Aramaic.
Translations into English and other languages of those later texts are very unreliable and often extremely misleading.
And don't get me started on the question of the apocrypha.
