Job isn't the first book in The Bible. Genesis is. It starts with "in the begining".
Job is the eighteenth book in the Old Testament. You may be thinking about the fact that some scholars find Job to be the earliest book in terms of a detailed discussion of a person and a semi-historical narrative (understand that this refers to the fact that Job is also poetic and contains teaching about God and suffering, not that it is non factual). The historical setting of Job is thought to precede Abraham.
It has also been contended by some that Job was the first book written, thus pre-dating the writings of Moses, but this may result from confusion between the historical setting of the book, which is clearly pre-Israel and the date of its possible composition. If it was written at the time of its setting it probably does pre-date Moses writings but others believe it to have been composed as late as the post-exilic period. Thus there is a wide range of views from the patriarchal to the post-exilic in terms of the date of composition.
In terms of its subject matter, it is clearly not describing the first moments of time as Genesis does, although God does rebuke Job and says 'where were you when I....etc'
thus speaking of His almighty creative power versus Job's finiteness.
The key markers which suggest (not prove) that Job is early are:
1. The absence of any mention of the history of Israel or its laws.
2. Job's long life of over 100 years, characteristic of that earlier period.
3. The role that Job played as a priest for his family -forbidden at the later period.
4. The use of livestock as a measurement of Job's wealth.
One of the difficulties with a late (post-exilic) date for the writing of Job is that it doesn't adequately explain the above features.
According to Nelsons Complete Book of Bible Maps and Charts, Thomas Nelson, 1993. p169,(also the source for the above 4 points) the majority of scholars today place the book between the Solomonic and post-exilic period.
