If you have a reasonably low criteria for accuracy you might say that its "accurate enough".
The problem some of us would have with that is the wild claims by some that this is the
inerrent, perfect, etc word of God. That we are to believe what it says over
any other evidence. Under those circumstances it's going to have to be held to a somewhat higher standard.
If we take the Bible as "close enough" then it is correct about a flood. That is, there have been pretty nasty floods here and there affecting local civilizations. However, that is
not what others claim as it's degree of accuracy.
If it's just as good a story as people of the time could manage then we have not complaints with it. Just tell that to those who think it should be injected into the science class rooms.
