Creationists claim that there was a great flood that covered all the Earth in water and that a man named Noah built a giant ark and saved all animal species by carrying them on it. However, there are many problems associated with such an idea. These range from problems with constructing the Ark itself, gathering the animals and problems in the geological record.
Building an ark of this size would have been extremely hard, if not impossible. The ark was supposed to be made out of wood, yet wood is not a very good ship building material. Today, the longest wooden ships are approximately 300 feet long while the Ark is supposed to be 450 feet long. Todayâ??s ships have iron reinforcing and have such horrendous leaks that they have to constantly pump water out of the ship to keep it afloat. If today, with our all our modern technological gadgets, we can barely keep a 300 foot ark afloat, then there is no way that a man living several thousands of years ago working with inferior technology could make a 450 foot ark (Dorman, et al.)
It would also be extremely hard to gather the animals. There are many different types of animals from all over the world. Noah could not gather all of them together into his Ark. Some species, like penguins, canâ??t even travel on land very fast. Many species lived in different climates and could not have survived the climate change. Other species, like Koalas, require a special diet to survive. All the animals could not have possibly lived near Noah. Even if the environment had been suitable to all animals (which, to date, no such an environment has ever been found) the increased competition from all the different species would have driven some extinct (Dorman, et al.).
A global flood would also have certain implications that differ from collected evidence. Ice cores from Greenland have been recovered and examined and show no evidence of a world wide flood. A world wide flood would leave air bubbles, changes in salinity and a layer of sediments. This flood should also have broken up the polar ice caps, yet they still exist. It would have taken a very long time for them to grow back, much longer than the time between now and when the flood supposedly occurred. The Greenland ice cap couldnâ??t even grow back under modern conditions (Dorman, et al.).
Many creationists claim that a large portion of species died off during the flood and that this accounts for the large number of fossils found. Once again, there are problems with this assertion. First, animals would probably die off in more or less random orders. The probability of them dying in a manner so that their fossils would be found to be consistent with evolution is extremely low. One would think that at least one dinosaur would have made it to the high grounds with other animals. There shouldnâ??t be any orderly pattern to it, yet there is (Godfrey, et al. 289). Coral reefs hundreds of feet thick and miles wide would not have had enough time to grow over fossils found beneath them. If humans with ship building existed at this time then some of their artifacts or fossils should have been found at much more varied depths, rather then the upper most part of the strata where they are found.
All these animals could not have possibly lived at the same time. Look at the Karoo formation in Africa, which contains the remnants of approximately 800 billion vertebrate animals. Robert E. Sloan, a paleontologist at the University of Minnesota has studied this formation and says that it contains creatures from the size of a small lizard to a cow. If we took each of these animals and evenly spread them throughout the Earth then there would be approximately seven for every Acre on Earth (Godfrey, et al. 289). If we assume, rather conservatively, that the Karoo formation contains 1% of the land fossils on Earth then there must have been 2100 creatures per acre at the time of the flood! Most creatures, let alone a human culture, cannot survive under the circumstances (Dorman, et al.).
If there was a world wide flood then many types of fish should have gone extinct. Rainwater has a different composition then other types of water and would have caused the composition of fishâ??s water to change. Many fish would die off if placed in water with different types of water (Dorman, et al.).
For several reasons it would have been hard for the people and animals in the Ark to survive (Godfrey, et al. 184). Sickness, short lifetimes and predators would have driven several species extinct.
The people in the Ark would have had to be extremely sick. Otherwise all the diseases would have died off. Measles, smallpox and typhus are among the diseases that would have had to be carried by humans. Otherwise these diseases would have become extinct. Other animals must have suffered from specific diseases as there are other diseases that attack specific animals only (Dorman, et al.).
Some short lived species should have become extinct. For example, adult mayflies live only a few days. Their larvae require shallow fresh running water to survive. If the story of Noahâ??s flood is true they should be extinct (Dorman, et al.).
Predators would also have gone extinct. Animals at the top of the food chain must eat animals lower then them to survive. If they had eaten the lower level species then they would be extinct (Dorman, et al.).
There would also be problems with putting the animals back into their respective habitats (Godfrey, et al. 184). Koalas would have had a hard time crossing the necessary oceans to get into Australia. Not to mention the number of species that live on islands. The necessary environments for these species did not exist between the point in which they left the ark and their eventual destination (Dorman, et al.).
