Monty,
There alot of mentally challenged individuals out there. If you are looking for scientific answers, there are some, to support the biblical flood. Bue the brainiacs above me mostly haven't got a clue.
I am a Christian AND a geologist and I have absolutely NO problem relating the two.
Orogeny is the process of mountain building. It has been going on since God created the earth. A mountain range can build in just a few months under the correct conditions. Take into account plate tectonics, an event that caused all of the moisture to leave the atmosphere in a global rain, and the melting of whatever ice was on the planet, and a planet that had very low mountains because of recent glaciation and it is possible.
In looking for a possible natural catastrophic cause of the great flood many theories have been proposed. Looking back at the Esquimaux tradition we note the following characteristics. High water, strong wind, high heat, large waves, uprooted and floating vegetation, and trembling cold. One possible scenario which might account for a majority of these factors is large amounts of volcanic type activity along portions of the subsurface ocean ridges for a short time.
Should greatly increased activity along the plate lines cause heating of the oceans along these lines there would be many large and terrible "super" storms which would greatly disturb the climate of the entire globe. NOAA is currently doing research on the subsurface plate lines and they have discovered many indicators of recent and current subsurface activity. And nearly all scientists agree that the materials along the subsurface spreading ridge lines are of recent origin. It is also possible that the flow could be of such a magnitude as to cause changes in the sea level. For example, the surface flow area of the Columbia lava plateau covers over 200,000 square miles and in places is up to a mile thick. Also possibly the polar ice caps would be temporarily melted. After the volcanic activity stopped there would be a transition period as climatic activity decreased and lesser affected areas of the extreme north and south continents would return to frigid climates, but with greatly increased moisture in the atmosphere it is theorized that an ice age would result.
We all know how catastrophic can be the effects of only a 3 degrees Centigrade increase of ocean surface temperature due to the past El Nino. When El Nino is active, a giant high pressure system centered near Easter Island drops slightly in pressure and touches off a change in Pacific currents, bringing warmer water in certain areas and colder water to others. An area 600 miles northwest of Easter Island was found to have 1133 seamounts and volcanoes, far more than any other area known on dry land or under the ocean. In 1995, scientists reported that a spate of undersea quakes and lava eruptions had preceded the onset of the El Nino cycle then in effect. Dr. Daniel A. Walker, a geophysicist at the University of Hawaii, said that the seismic activity was the most unusual it had been in 30 years and tentatively linked it to El Nino. Greater increases on a global scale would obviously cause destruction of a greater magnitude.
Using available computer simulation models it is possible to a limited extent to simulate the possible rainfall effects of the theorized condition. Of course, there have been many proposed theories as to the configuration of the global surface at the time of the flood, but for now it is convenient to assume that this configuration was as it is today. Fig 3 below shows one possible rainfall configuration for the Mediterranean area as we know it today which is shown as a visual reference. And Fig 4 below shows one very limited computer simulation in which global rainfall amounts are shown to be increased up to 10 times.
To greatly increase the amount of water on the earth would require a rather large size object since the earth presently has approximately 340 x 10*6 cubic miles of water. A Pluto-type ice sphere of 320 miles in diameter would increase the water on the earth by about 5 percent. Pluto itself is 1450 miles in diameter. One comet that recently visited our skies was about 25 miles wide. It would be hard to imagine the catastrophic destruction that the impact of a 320-mile wide ice comet would cause to planet Earth.
More reasonable would seem to be a swarm of small ice comets over a few days time period. Quite possibly the Earth in its orbit could enter a band of small ice comets which shower the Earth with a considerable amount of water in a few days time period. Or also there is the possibilty of the Earth orbit encountering the remains of a large comet that was broken up by impacts or encounters with the outer planets or their gravitational forces, or as will be shown below, a comet broken up by the heating effects of our Sun. Theoretically the larger outer planets such as Jupiter and Saturn work like sweepers to clean up a lot of the space trash before it comes into the neighborhood of our lesser planet Earth. For example the comet Shoemaker-Levy 9 impacted Jupiter over a period of 7 days (July 16 - July 22, 1994) with 20+ observable fragments.
"Rabbi Moses Ben Nachman, a Jew living in Spain, wrote of God taking two stars from Khima and throwing them at the earth in order to begin the great flood. (from "Comets in Ancient Cultures" By Noah Goldman U. Maryland, College Park Scholars) An indicator that the flood comet appeared in the sky as a twin comet.
After being broken up and dispersed by the heating effects of the sun while still in space the fragmented comet must enter our atmosphere which is very hard on intruding high speed space objects! A very large percentage of them are broken up or "exploded" by the experience. Even iron meteorites such as the Gibeon meteorite, 90% iron, which was apparently a large object that burst high in the atmosphere and produced a debris field 70 miles (120 km) wide by 230 miles (390k km) long. The breakup was so complete that no major craters have ever been identified even though many masses between 100 and 500 kg have been found, and in the past few years an increasing number of small Gibeon meteorites have been located as modern metal detection equipment has allowed meteorite hunters to find the smaller specimens. (see news stories on latest meteorite shower) The majority of comet material would be considerably more fragile than that of most meteorites or asteroids.
It should also be noted that any natural cause for the flood must be relatively short-lived. In order for the larger animals and humans to survive, the area where they landed should return to near normal in just a few seasons. The Biblical chronology requires the heavy rains to stop after 40 days and for land to become dry enough for the occupants of the ark to emerge after 1 year and 17 days. After 11 months and 18 days plant growth has to have reappeared when the dove returned with a plucked leaf. And within a short time Noah was able to plant and harvest a vineyard. If the ocean waters were heated considerably due to subsurface volcanic activity along the mid-ocean ridges as proposed, it would take a relatively long time for ocean cooling back to near normal, possibly as long as 500 years or more.
How long it would take to return to near normal growing seasons due to an ice comet shower would seem to depend upon the size and number of comet fragments and the percentage of solid material versus water contained within the comets. The larger the number of fragments, the smaller the fragments and the higher the percentage of water, the faster the Earth atmosphere and surface could return to normal. The heavy rainfall from that portion of the comet's water that vaporized in the atmosphere would clean the air and minimize the effect of dust clouding from land impacts. Assuming a nearly optimal comet shower condition, probably portions of the Earth could return to normal growing seasons in a relatively short time, say within a decade or less. Since the major portion of the Earth surface is water, the probabilities are that most of the comet material that did not turn to vapor in the atmosphere and reached the surface would impact on water covered areas. This would not be inconsistent with the wording of the Scriptures since the Hebrew words translated as "fountains of the great deep broken up", can also be translated as "cleaved". In fact "to cleave" is the basic meaning of this Hebrew word "baqa" (Strong's # 1234), which is the opening up of an object due to a striking. The ice comet shower would also seem to better fit the Biblical record in that the heavy rains and great disturbances to the seas would start in a very short time after the impact of the first fragment with the atmosphere and the seas, and the heavy rains and the disturbances to the waters would start to decrease not long after the last major fragment had impacted. Therefore, if a high water content comet much larger than Shoemaker-Levy 9 was fragmented into say 100+ major fragments and many, many smaller fragments and impacted the Earth over approximately 40 days the result would seem to closely fit the Biblical record.
I hope this helps you...personally, I don't try to bend my mind around God's actions...it hurts too much to try. I just accept His Word as absolute truth. Just because I cant explain it doesnt mean it aint true...heh.
