There are over 300 cultures scattered throughout the world that have a worldwide flood story. Coincidence? I think not. "Hawaiians have a flood story that tells of a time when, long after the death of the first man, the world became a wicked, terrible place. Only one good man was left, and his name was Nu-u. He made a great canoe with a house on it and filled it with animals. In this story, the waters came up over all the earth and killed all the people; only Nu-u and his family were saved.

Another flood story is from China. It records that Fuhi, his wife, three sons, and three daughters escaped a great flood and were the only people alive on earth. After the great flood, they repopulated the world.

As the story of the Flood was verbally passed from one generation to the next, some aspects would have been lost or altered. And this is what has happened, as we can see from the chart. However, as seen in the given examples, each story shares remarkable similarities to the account of Noah in the Bible. This is true even in some of the details, such as the name Nu-u in the Hawaiian flood story. “Nu-u” is very similar to “Noah.”" 

Sorry, I don't have time to read the whole thing, but after reading that short snippet, one thing pops up in my mind. Why would you assume that the story of Noah's Ark is the true version of this story? Why not the story of Nu-u? What if there just was a great flood, and everyone decided to write their own story about it? What makes the version in the Bible the correct one?

If you read the end that is the basic idea behind the whole topic.
