The Bible proceeds the Torah. If I recall the first written record of the Torah, other than the dead sea scrolls, is circa 800AD. The discovery of the dead sea scrolls is highly suspect, and those portions that have escaped Israeli control have proven to have been fabricated forgeries that were made to look older than they actually were. But if you want to believe that an oral Torah was passed down nearly verbatim over a thousand years, I guess you can do that.
