The hard-core fundamentalists love forwarding links to sites like this one, alleging to provide archeological proof of various fantasies from The Bible -- such as Noah's Ark.
Here is a good resource for understanding the bunk behind these alleged findings.
What's funny, I think is how they keep finding Noah's Ark. It seems one time just wasn't enough! Check this link for more.
Anyway, even Answers in Genesis knows all this Ark nonsense is totally absurd.
But, if you still need to know more, this is a great link on the science that would be necessary for a global flood. And even if you only believe half of the science, the story is still ridiculous.
Just like other flood stories we all know are fiction, like Atlantis.
