Implausibility of the flood tale

[Zzyzx]

.
In a thread discussing the different lengths of time Genesis assigns to the Earth being flooded, mention was made of other implausibilities of the flood tale -- including:

1) A wooden boat much larger that any known to exist and built by a 500 year old man
2) Millions of animals gathered from all over the world and redistributed afterward
3) A billion cubic miles of water sudden appearing -- then disappearing afterward
4) Eight people providing for millions of diverse animals (some carnivores) for a year
5) Repopulating all the continents with humans and other animals in a few thousand years (and producing the great genetic diversity known to exist).

Are those (and other) implausibilities sufficient grounds to conclude that in all likelihood the flood tale is fable, legend, myth, folklore or fiction?

If not, why not? What rational explanation can be made for them?
