Dating Scripture

Psalms 74:7 (KJV) They have cast fire into thy sanctuary, they have defiled by casting down the dwelling place of thy name to the ground.

(Proverbs 29 also read)

Today you get to play scholar.  As you read this verse, what period in the history of Israel fits what you are reading?  Put aside your pre-conceived ideas.  Suspend your assumption that all Psalms are written by David.  When was God’s sanctuary burned to the ground?

It would seem to be speaking of the destruction of the temple by the Babylonians.  That would mean that the book of Psalms had additions at least that late in Israel’s history.

So?  Take the Bible as it presents itself, not as others interpret it for you.  Be your own scholar.
