who scoff at the Bible are "willingly ignorant" of the Creation and the Flood. In order to understand science and the Bible, we must not be ignorant of those two great events in Earth's history.
1. Over 500 Flood legends from all parts of the world have been found. Most have similarities to the Genesis account.
2. Noah's ark was built only to float, not to sail anywhere. Many ark scholars believe that the ark was a "barge" shape, not a pointed "boat" shape. This would greatly increase the cargo capacity. Scoffers have pointed out that the largest sailing ships were less than 300 feet because of the problem of twisting and flexing the boat. These ships had giant masts and sails to catch the wind. Noah's ark needed neither of those and therefore had far less torsional stress.
3. Even using the small 18-inch cubit (my height is 6'1" and I have a 21-inch cubit), the ark was large enough to hold all the required animals, people, and food with room to spare.
