Actually, the old testament can also be viewed as more political propaganda than accurate historical treatise.
I invite you to compare various events reported in the bible to the accounts from the Babylonian and Assyrian historical texts. For example, the Assyrians tell us that Egyptian agitators convinced the kingdoms of Judea and Israel, along with the Phoenician states, to divert their tribute (i.e. monetary payments) from the Assyrian Empire to the Egyptian Empire. The Assyrians responded militarily and, following their traditional practice, relocated the troublemakers. The bible, however, only provides the point-of-view of the injured parties, completely ignoring the political reality, and puts a weird (now enshrined) religious spin on the whole thing.
Just one example, there are many more. You can find translations of Mesopotamian history on the shelves of any decent research university.
