If the account of Noah's flood isn't true, then how is it possible that we have found Noah's Ark split up into three pieces?

Right. This is the trouble with only listening to apologists. They spin tales of garbage because it's exactly what people want to hear, and they bank on the audience not checking it out for themselves.
