You may have heard that before the Genesis document (of the bible) was written there was a flood story circulating in West Asia.
If your short of time, here's a 5 minute video by Irving Finkel discussing a Flood story document written in cuneiform.

Of course, the Christian argument may be that the Bible had the original (truthful) version and the cuneiform story came later.
But that's so difficult to prove. We can locate the approximate time that the cuneiform version was written, but we have no ancient versions of the Genesis document that go back to that time. All the extant versions are much later.
And, if we accept the JW/WTS perspective on Genesis, i.e. that Moses wrote it based on earlier documents, we need to ask what kind of documents were they and who wrote them? The WT publication, 'Aid to Bible Understanding,' claim's Moses was born about 1593 BCE.
