Try this one on.....long read but...I will supply the link:
Creationist models are often criticized for being too vague to have any predictive value. A literal interpretation of the Flood story in Genesis, however, does imply certain physical consequences which can be tested against what we actually observe, and the implications of such an interpretation are investigated below. Some creationists provided even more detailed models, and these are also addressed (see especially sections 5 and 7).
References are listed at the end of each section.
Two kinds of flood model are not addressed here. First is the local flood. Genesis 6-8 can be interpreted as a homiletic story such that the "world" that was flooded was just the area that Noah knew. Creationists argue against the local flood model because it doesn't fit their own literalist preconceptions, but I know of no physical evidence contrary to such a model.
Second, the whole story can be dismissed as a series of supernatural miracles. There is no way to contradict such an argument. However, one must wonder about a God who reportedly does one thing and then arranges every bit of evidence to make it look like something else happened. It's entirely possible that a global flood occurred 4000 years ago or even last Thursday, and that God subsequently erased all the evidence, including our memories of it. But even if such stories are true, what's the point?
1. Building the Ark
Wood is not the best material for shipbuilding. It is not enough that a ship be built to hold together; it must also be sturdy enough that the changing stresses don't open gaps in its hull. Wood is simply not strong enough to prevent separation between the joints, especially in the heavy seas that the Ark would have encountered. The longest wooden ships in modern seas are about 300 feet, and these require reinforcing with iron straps and leak so badly they must be constantly pumped. The ark was 450 feet long [ Gen. 6:15]. Could an ark that size be made seaworthy?
2. Gathering the Animals
Bringing all kinds of animals together in the vicinity of the ark presents significant problems.
Could animals have traveled from elsewhere? If the animals traveled from other parts of the world, many of them would have faced extreme difficulties.
* Some, like sloths and penguins, can't travel overland very well at all.
* Some, like koalas and many insects, require a special diet. How did they bring it along?
* Some cave-dwelling arthropods can't survive in less than 100% relative humidity.
* Some, like dodos, must have lived on islands. If they didn't, they would have been easy prey for other animals. When mainland species like rats or pigs are introduced to islands, they drive many indigenous species to extinction. Those species would not have been able to survive such competition if they lived where mainland species could get at them before the Flood.
Could animals have all lived near Noah? Some creationists suggest that the animals need not have traveled far to reach the Ark; a moderate climate could have made it possible for all of them to live nearby all along. However, this proposal makes matters even worse. The last point above would have applied not only to island species, but to almost all species. Competition between species would have driven most of them to extinction.
There is a reason why Gila monsters, yaks, and quetzals don't all live together in a temperate climate. They can't survive there, at least not for long without special care. Organisms have preferred environments outside of which they are at a deadly disadvantage. Most extinctions are caused by destroying the organisms' preferred environments. The creationists who propose all the species living together in a uniform climate are effectively proposing the destruction of all environments but one. Not many species could have survived that.
How was the Ark loaded? Getting all the animals aboard the Ark presents logistical problems which, while not impossible, are highly impractical. Noah had only seven days to load the Ark ( Gen. 7:4-10). If only 15764 animals were aboard the Ark (see section 3), one animal must have been loaded every 38 seconds, without letup. Since there were likely more animals to load, the time pressures would have been even worse.
3. Fitting the Animals Aboard
To determine how much space is required for animals, we must first determine what is a kind, how many kinds were aboard the ark, and how big they were.
What is a kind? Creationists themselves can't decide on an answer to this question; they propose criteria ranging from species to order, and I have even seen an entire kingdom (bacteria) suggested as a single kind. Woodmorappe (p. 5-7) compromises by using genus as a kind. However, on the ark "kind" must have meant something closer to species for three reasons:
* For purposes of naming animals, the people who live among them distinguish between them (that is, give them different names) at roughly the species level. [Gould, 1980]
* The Biblical "kind," according to most interpretations, implies reproductive separateness. On the ark, the purpose of gathering different kinds was to preserve them by later reproduction. Species, by definition, is the level at which animals are reproductively distinct.
* The Flood, according to models, was fairly recent. There simply wouldn't have been time enough to accumulate the number of mutations necessary for the diversity of species we see within many genera today.
What kinds were aboard the ark? Woodmorappe and Whitcomb & Morris arbitrarily exclude all animals except mammals, birds, and reptiles. However, many other animals, particularly land arthropods, must also have been on the ark for two reasons:
* The Bible says so. Gen. 7:8 puts on the ark all creatures that move along the ground, with no further qualifications. Lev. 11:42 includes arthropods (creatures that "walk on many feet") in such a category.
* They couldn't survive outside. Gen. 7:21-23 says every land creature not aboard the ark perished. And indeed, not one insect species in a thousand could survive for half a year on the vegetation mats proposed by some creationists. Most other land arthropods, snails, slugs, earthworms, etc. would also have to be on the ark to survive.
Were dinosaurs and other extinct animals on the ark? According to the Bible, Noah took samples of all animals alive at the time of the Flood. If, as creationists claim, all fossil-bearing strata were deposited by the Flood, then all the animals which became fossils were alive then. Therefore all extinct land animals had representatives aboard the ark.
It is also worth pointing out that the number of extinct species is undoubtedly greater than the number of known extinct species. New genera of dinosaurs have been discovered at a nearly constant rate for more than a century, and there's no indication that the rate of discovery will fall off in the near future.

, I would have to agree. Most creationist don't have an understanding of science or biology, and it does make those of us who can be considered creationists (by some definitions) seem in-credible as well.
