So, we take the silly story of Gilgamesh as the true account, a round raft of reeds, rather than the Bible? "Well, it's older, of course" which really, it isn't. Consider that Moses didn't so much write the account of the flood, but more likely compiled the writings of Noah who recorded it at the time of the event. And even if Moses wrote it, it would have been at the direction of God, who gave him the information-and I think we could trust that account as faithful. No, the Ark was as explained in the book of Genesis, and really, it still probably wasn't shaped like a boat, but a rectangular box-after all, the word 'ark' means a box. They are right, it didn't have to go anywhere, just stay afloat. And there are numerous other accounts of the flood in many different cultures, all a little different, but all essentially have the same elements: a world-wide flood, a boat, some survivors found righteous by God, and the saving of the animals. BY cultures who never knew each other-we think, unless they all come from those who are related to those who came from the ark, and carried the story with them, each reflecting their version as they rejected God for another idol.

Noah's Ark was actually square shaped, like a long square..

The ark never existed, so why does the shape of it matter?

Sorry, but the flood could never have happened, the ark, the animals, none of it is possible. http://www.truth-saves.com/Never_a_Flood.php

Its length was 300 cubits (450 feet, or 135 meters); its width was 50 cubits (75 feet, or 22.5 meters); it had three stories and its height was 30 cubits (45 feet, or 13.5 meters). Try fitting that in a circle!
