Young-Earth Creationism

1. Where did all the water come from?The "fountains of the great deep" are mentioned before the "windows of heaven," indicating either relative importance or the order of events.What are the "fountains of the great deep?" This phrase is used only in Genesis 7:11. "Fountains of the deep" is used in Genesis 8:2, where it clearly refers to the same thing, and Proverbs 8:28, where the precise meaning is not clear. "The great deep" is used three other times: Isaiah 51:10, where it clearly refers to the ocean; Amos 7:4, where God"s fire of judgement is said to dry up the great deep, probably the oceans; and Psalm 36:6 where it is used metaphorically of the depth of God"s justice/judgement. "The deep" is used more often, and usually refers to the oceans (e.g., Genesis 1:2; Job 38:30, 41:32; Psalm 42:7, 104:6; Isaiah 51:10, 63:13; Ezekiel 26:19; Jonah 2:3), but sometimes to subterranean sources of water (Ezekiel 31:4, 15). The Hebrew word (mayan) translated "fountains" means "fountain, spring, well."12. How did the animals fit into a boat 1/3 the Titanic's size? One commonly raised problem is "How could you fit all those huge dinosaurs on the Ark?" First, of the 668 supposed dinosaur genera, only 106 weighed more than ten tons when fully grown. Second, as said above, the number of dinosaur genera is probably greatly exaggerated. But these numbers are granted by Woodmorappe to be generous to skeptics. Third, the Bible does not say that the animals had to be fully grown. The largest animals were probably represented by "teenage" or even younger specimens. The median size of all animals on the ark would actually have been that of a small rat, according to Woodmorappe"s up-to-date tabulations, while only about 11% would have been much larger than a sheep.3. How did humanity repopulate with a only few incestuous humans in 4000 years?Now, the way it's been explained to me is that all human civilization arose post-Flood. Using ages and dates in the Bible it's possible to determine the exact year (starting from the creation of Adam at 4026 BCE):From Adam's creation to the birth of Seth 130 yearsThen to the birth of Enosh 105 yearsTo the birth of Kenan 90 yearsTo the birth of Mahalalel 70 yearsTo the birth of Jared 65 yearsTo the birth of Enoch 162 yearsTo the birth of Methuselah 65 yearsTo the birth of Lamech 187 yearsTo the birth of Noah 182 yearsTo the Flood 600 yearsThanks to Bible geneology and chronology, the flood can be pinned to 2370 BCE, roughly 4,400 years ago as you said.Anyhow, the progenitors of the modern human race were Ham, Shem and Japheth, Noah's three sons and their wives. They were fruitful and multiplied after the flood down to around the time of Peleg when the Tower of Babel was built. The building of the tower lead to the dispersion of various ethnic and language groups to all corners of the Earth and the rest, as they say, is history.It's impossible to work out from the Bible the exact time of the Tower of Babel, but it's estimated to be somewhere in the neighborhood of 180 years after the flood based on when Peleg lived.Now, the earliest known Egyptian pyramid (the Step Pyramid) has been dated to about 300 years prior to this date, the slightly later Red Pyramid, Bent Pyramid and (of course) the Giza Pyramids and the Sphinx are all generally dated as occuring before the Biblical flood date as well. Of course, these datings must be off by somewhere in the neighborhood of 500 years or so in order for their construction to have occured post-Tower of Babel. So, presuming thats the case the next question is how many people needed to be alive in Egypt at the time of the pyramids construction in order to facilitate said construction? It's really impossible to tell for certain, but the generally accepted estimate is around 1-2 million people living in Egypt at the time and a pyramid building workforce around 20,000 people.It's not only Egypt that needs to be accounted for, of course. The entire fertile crescent region, Sumeria, Accadia, Babylon itself, that entire region was likewise populated shortly after the flood and a lot of cities were built indicating minimally hundreds of thousands, likely millions more people.In China, by around 2100 BCE (admittedly nearly 300 years after the flood) the earliest recorded records of a Xia dynasty are known to exist. So, presumably the China-bound descendants of the flood survivors, when scattered at Babel, took a while to migrate over there and then developed their culture. There were, apparently, tens or possibly hundreds of thousands of people in China at this time as well.So, in an effort to determine if I could stick the to realities of human biology and postulate a repopulation scenario, I wrote a computer program today (I'm a programmer). I made many unreasonable assumptions by modern standards but I assumed that God would be using miraculous abilities to accelerate and support the repopulation effort. My program takes various parameters but it starts with the initial condition that 6 breeding pairs of humans (the Bible doesn't indicate that Noah and his wife had more children than the three) began to procreate at the fastest rate they could. The reproduction was divinely supported to be as effective as possible.4. How did animals repopulate?Skeptics often claim, "The Bible is not a science textbook." This, of course, is true"because science textbooks change every year, whereas the Bible is the unchanging Word of God"the God who cannot lie. Nevertheless, the Bible can be relied upon when it touches on every scientific issue, including ecology. It is the Bible that gives us the big picture. Within this big picture, we can build scientific models that help us explain how past events may have come about. Such models should be held to lightly, but the Scripture to which they refer is inerrant. That is to say future research may cast doubt on an actual model, without casting doubt on Scripture.With this in mind, the question needs to be asked, "Is there a Bible-based model that we can use to help explain how animals might have migrated from where the Ark landed to where they live today?" The answer is yes. Animals repopulate fast since some can have up to 100 babies.
