Why is the book of Judith historically inaccurate?

[NathanH83]

I mean, Judith chapter 4 seems to say that the story takes place after the captivity, after they returned from captivity (70 years later), after the temple was rebuilt, and after the temple was polluted and re-dedicated.

So couldn’t it just be talking about a different Nebuchadnezzar who ruled Assyria at a later point in time?

I mean, Assyria existed later on, didn’t it?

 

[NewCreation435]

This is what Wikipedia says of it though I have not read the book of Judith myself since it isn't in the Protestant Bible

"Although it was likely written by a Jew during the Second Temple period, there is no evidence that the Book of Judith was ever considered authoritative or a candidate for canonicity by any Jewish group.[4][5]

The Masoretic Text of the Hebrew Bible does not contain it, nor was it found among the Dead Sea Scrolls or referred to in any early Rabbinic literature.[5][6]

Reasons for its exclusion include the lateness of its composition, possible Greek origin, open support of the Hasmonean dynasty (to which the early rabbinate was opposed), and perhaps the brash and seductive character of Judith herself."
