The Holy Bible - fact or fiction?

If the Bible says something happened and it actually did, you still don't believe that the flood happened?

There is a vast gap between the bible saying something happened and knowing that it actually happened. We have no evidence that a worldwide flood occurred, and the bible claiming that it did is of no consequence. There is plenty of literature, holy and secular, from ages past that claim all sorts of things. That something "says" that something happened, particularly from this time period, is no guarantee that it did occur.

Since it did, read the Bible section about the flood that God told Noah  years before  it occurred.

We have no evidence that either event happened. Do we know that God told Noah of the flood before it occurred? This is all written in the past tense. I could write a book today saying that I predicted World War II. That would be no example of prophecy as there's no evidence that I knew about the event before it occurred. Likewise we have no real evidence that Noah knew of the impending flood before it happened. It's all written from the perspective of events that had already happened. What we do know is that the books of the old testament were finalized sometime between 1200 BCE and the common era, and that the new testament was written between the first and second centuries of the common era. For an example from the bible to be valid prophecy, the event would have to occur between the writing of it in the bible, and the present day. The book of Daniel is instructive in this regard. It claims to have been written during the Babylonian captivity, which would make its foretelling of certain events a valid example of prophecy. However, the oldest copy of the book of Daniel that we have dates to about 150 BCE, post-dating the events foretold. On the basis of this, it's impossible to determine whether Daniel is valid prophecy or not. Internal evidence from the book suggest that rather than predating events as the book claims, it was actually written about the same time as the events which it is "foretelling." Unlike the valid question of the prophetic nature of Daniel, the tale of Noah is told from the perspective of an author writing long after the events that are claimed to have occurred.

There is an additional difficulty in the tale of Noah in the question of where did the author of Genesis get his information regarding what God told Noah beforehand? Tradition ascribes authorship of Genesis to Moses. So Moses either got his information from God, or from oral history. Neither source is specified in the text, so it's impossible to say with any surety that the tale as told is reliable. Supposedly, God can tell no lie. However, oral tradition is another matter. It's anybody's guess whether the tale as recorded actually occurred in the manner that it is told in Genesis.
