* Over 250 Flood legends from all parts of the world have been found. Most have similarities to the Genesis story.
* 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 on them and sails to catch the wind. Noah's ark need neither of those and therefore had far less torsional stress.
* Even using the small 18-inch cubit (my height is 6-ft. 1-in. and I have a 21-in. cubit) the ark was large enough to hold all the required animals, people, and food with room to spare.
* The length-to-width ratio of 6 to 1 is what shipbuilders today often use. This is the best ratio for stability in stormy weather.
* God told Noah to bring two of each kind (seven of some), not of each species or variety. Noah had only two of the dog kind which would include the wolves, coyotes, foxes, mutts, etc. The "kind" grouping is probably closer to our modern family division in taxonomy, and would greatly reduce the number of animals on the ark. Animals have diversified into many varieties in the last 4400 years since the Flood. This diversification is not anything similar to great claims that the evolutionists teach.
* Only land-dwelling, air-breathing animals had to be included on the ark (Gen. 7:15, "in which is the breath of life," 7:22). Noah did not need to bring all the thousands of insects varieties.
* Many animals sleep, hibernate, or become very inactive during bad weather.
* The large mountains, as we have them today, did not exist until after the Flood when "the mountains arose and the valleys sank down" (Ps. 104:5-9, Gen. 8:3-8).
* There is enough water in the oceans right now to cover the earth 8,000 feet deep if the surface of the earth were smooth.
* The top 3,000 feet of Mt. Everest (from 26,000-29,000 feet) is made up of sedimentary rock packed with seashells and other ocean-dwelling animals.
* Sedimentary rock is found all over the world. Sedimentary rock is formed in water.
* Petrified clams in the closed position (found all over the world) testify to their rapid burial while they were still alive, even on top of Mount Everest.
* Bent rock layers, fossil graveyards, and poly-strata fossils are best explained by a Flood.
