The Books of Genesis tells different stories and are of that reason different. However they do both contain creation material.
Genesis contains two complete creation stories, at Genesis 1:1-2:4a and 2:4b-2:20. Some scholars think of Genesis chapter 5 as possibly a third creation story.
Job contains fragments of a much more primitive creation story, especially in chapter 38ff, where God querulously asked Job where he was when God created the world and if he is so righteous that he could do any of the things that God had done. Here we see suggestions of how at the time of creation God had to fight the chaos monsters, for example the behemoth and the leviathan. Chaos monsters were once closely associated with many creation stories of the Near East.
Jewish answer:
The books of Genesis and Job are two different things. Genesis recounts the events of the Creation, the Flood, and the lives of the righteous, from Abraham through Joseph.
Job is a poetic prophecy concerning the question of the suffering of the righteous.
The Book of Job is undoubtedly a parable: who could really know what God said to Satan in heaven, or what angry duscussions he had with Job, when his attempts to test Job failed? As there is no possibiliity the story is genuinely historical, there is no possibility Job was a real person. The Job briefly mentioned in Genesis 46:13 as a descendant of Jacob might also have been fictional, since we have no historical evidence for his existence. Whatever the case, the Bible makes no attempt to link the two men. We should see them as two different people.
Job.
Some scholars believe the book of Job to be written before Genesis. However, if speaking about the time of the events then Genesis comes first. Well, actually, the intro in John would come first then Genesis. Go see the book of John for yourself to see what I'm talking about.
Job, but it depends on which type of 'oldest' is meant. Job was probably the oldest book written, but Genesis is the oldest chronologically, as in content. Job was probably born in 2900BC and lived for 248 years ie to 2648 BC [as dated by B. Setterfield], while Genesis was written by Moses (1486BC-1406BC : as dated by Ussher) and opens with the Creation of the Earth in 4004BC (Ussher).
There's about 38,000 words there, depending on the version.
