Some of their scriptures are older. Some claim to be much older than we can prove, but some definitely pre-date the Bible. However, “better” is a judgement call, and isn’t something which can be proved or disproved. I find the Hindu scriptures entertaining; with vimana in the sky, magic weapons, rakshasas and demons, monkey armies, etc. I even think that some of them have wisdom similar to the Bible, but it is in the Bible where I find God.
Back to the OP; Job is believed to be the oldest book in the Bible. I have never met a Jewish person, rabbi or otherwise, who thinks that it’s a literal story. There are certain problems with it, like God making a bet with the devil over the fate of someone’s soul and their happiness. It was meant to be a story to teach us that we often don’t understand the motives of God, because only He sees the big picture.
There is some argument over the historicity of the Maccabees, but I believe that they are at least based on history. I find it interesting that contemporary sources, when looking for the Ark of the Covenant, never go back to the Maccabees which tells us where it was hidden (or at least a general area.) Some things from other books which were thought to not be historical, such as the existence of David and Solomon, have since been proven by archaeology. It’s impossible to say how much of the Old Testament is historically accurate, but it was at least based in real history. Kings and Chronicles were written as historical texts, so they’re probably pretty accurate, as far as anyone can tell.
