Nonsense of Noah
Ten generations after Adam, his descendents would still be in the stone age. There are still primitive tribes today who have had no contact with the outside world (as would have been the case with Noah - there WAS no outside world) and they are literally still in the stone age. Therefore, Noah did not have access to the technology that would have been required to build an Ark.
CNN ran this story "'Uncontacted tribe' sighted in Amazon" in May of 2008:
Researchers have produced aerial photos of jungle dwellers who they say are among the few remaining peoples on Earth who have had no contact with the outside world.
Here's the picture that ran with the story. Here's what people look like if they are not exposed to "civilization".
They are obviously more than 10 generations from their creation. Do they look like they could build a 450' x 75' x 45' Ark?

This introduction to the website Native Americans .com has this to say about the history of the Native American Indian:
LONG BEFORE the white man set foot on American soil, the American Indians, or rather the Native Americans, had been living in America. When the Europeans came here, there were probably about 10 million Indians populating America north of present-day Mexico. And they had been living in America for quite some time. It is believed that the first Native Americans arrived during the last ice-age, approximately 20,000 - 30,000 years ago through a land-bridge across the Bering Sound, from northeastern Siberia into Alaska. The oldest documented Indian cultures in North America are Sandia (15000 BC), Clovis (12000 BC) and Folsom (8000 BC)
Thus, 25,000 years (and conservitively 1000 generations) after arriving on the continent, there were only 10 million Indians and they were still in the Stone Age! There's no telling how many generations preceded those who came to America.
Noah, only 10 generations removed from the time where there were only TWO people on the earth could not have been any further advanced than the American Indian. AND, he was a product of significant inbreeding.
Where did the tools to ...
Cut the timbers
Remember, there were no metal saws, iron hammers, screws, drills, rope, planes; in a word - NO TOOLS.
Probably not even a wheel.
Noah was a hunter-gather, just trying to survive. God did not give him explicit instructions about how to build the Ark. The ONLY instructions Noah received from God were the dimensions of the Ark, the number of levels and that it should have a door and an 18" x 18" window.
How in the world does this stone-age man know how to build a ship the size of the Ark without any other instructions?
He didn't even have paper upon which to record thoughts about the design.
If the wheel was invented around 5000 BC - before Adam, but if 5000 BC never happened, did the wheel exist in Noah's time? It's important because building the Ark without carts and other wheeled devices would add one more impossibility to the task.
Most authorities regard the wheel as one of the oldest and most important inventions, which originated in ancient Mesopotamia in the 5th millennium BC originally in the function of potter's wheels. Near the northern side of the Caucasus several graves were found, in which since 3700 BC people had been buried on wagons or carts (both types). The earliest depiction of what may be a wheeled vehicle (here a wagon-four wheels, two axles), is on the Bronocice pot, a ca. 3500 BC clay pot excavated in southern Poland.
Apparently, the idea of a wheel as a means of transportation didn't occur until a thousand years later.
