This a direct quote from the Smithsonian Department of Anthropology from article two.
As stated, it is seen as accurate as any book of its time, with all of the innacuracies that come with stories written in that era. Obviously the Greek gods didn't really give Helen of Troy to a different man sparking the conflict, yet we know the war for Troy happened. The same can be said about many of the Biblical events, with much of the nook up to the belief system of the reader.
I will also add. I am not here to debate whether or not the Bible is true, I am simply defending its validity as a historical document. Anything more shall be left up to scholars and intelecuals and best not discussed on a Lego Forum on the internet.
