Comment on Panda’s Thumb: ‘SDAs are split over evolution’ by krissmith777.

@Sean Pitman

And you’ve got your Panthalasia Ocean already in existence then? – over 200 million years ago? The start of the formation of the Atlantic Ocean some 135 million years ago hardly solves your problem as the current sediment load within all the ocean basins can be explained with just 15 million years at current sedimentation rates…

I never said “all.” You did. I’m not so presumtuous as to make such a foolish assumption.

at current sedimentation rates

Yeah…how young earthers always throw around the “current rate” argument… I’ll just tell you what I should have in the first place: It’s a strawman. I have already said that there is no rule saying that the rates of sedimentation and erosion are constant. Rates of sedimentation are not “fixed.” It’s not like radiometric dating methods that have a predictable rate of decay. It is much more possible for erosion and sedimentation rates to be changed, excelerated and even slowed down by the surrounding conditions than it is for the same to happen to radiometric decay.

IT has not been demonstrated that the rate has remained static.

This paper doesn’t deal with the overall sediment load being delivered to the oceans at all. Arguing that small particles sink more slowly than large particules does not explain why there is so little sediment on the ocean floors given a delivery rate of 30 billion tons of sediment per year…

You missed my overall point. The first sentence I quoted from it was: The rates at which sediments accumulate vary enormously, owing to the natural variability of the processes that produce and transport sediments. — The rates vary greatly depending on the conditions… Your argument pre-supposes that the rate has not changed, and you have not demonstrated that it has. — And frankly, it doesn’t have to be. — David E. Thomas says it much better than I ever could:

…much sediment never gets to the ocean floor, but is trapped instead on continental slopes and shelves, or in huge river deltas. Over the years, some of these continental slopes can accumulate several kilometers of sediment, while others can even become part of mountain ranges in continental plate-to-plate collisions. Neither erosion nor subduction are expected to be constant processes over millions of years, and they are simply not good clocks.

I heard one geologist call it a “crude” dating method. Looks more related to “relative dating,” not “absolute dating.”

Again, that is completely irrelevant to the point that the total amount of sediment, the total tonnage that is current in the oceans, irrespective of its location within the ocean basins, can be explained given just 15 million years…

And the paper I linked a while ago using the current rate gave the figure of 100 million years: (“At a rate of 0.5 cm (.2 in)/1000 years, it takes only 100 million years to accumulate 500 m (1600 ft) of sediment,”)

If the majority of the sediment were deposited very rapidly via very high level water runoff after the Flood, the majority of the sediment would be deposited close to the continents and on the continental shelves. As the continents moved rapidly away from each other at first, the level of sedimentation would have declined to the current level rapidly over time leaving much less sediment for the mid regions of the oceans – as we see today.

This is an ad hoc explanation, and it cannot be falsified even if it were not true. This is why Geologists do not take “flood geology” seriously. Also, it begs the question why the sea floor doesn’t consistently show the same age.

Again, you’re forgetting about the catastrophic nature of the Flood model and its aftermath. Sediment can be eroded very very quickly during and after a catastrophic Flooding and break-up of the continents…

The flood models proposed by some creation scientists really bother me, and even assuming that the flood was a global event, it’s hard for me to reconcile EVEN THEM with the global flood itself… In particular, John Baumgrdner’s “Runaway Subduction” bothers me. The tectonic activity required by his model would have caused major earthquakes which, in tern, would have caused huge tsunamis. My problem with harmonizing this model with even a global flood is that the bible indicates that the storm was over 40 days after it started. But Noah would still have had massive tsunamis to deal with as the plates would still be moving extremely rapidly. I know it just says that the rain was what stopped, but it is hard to say the storm is over if that is ALL that ended.

Besides, the energy that his model requires 10^28 joules..which is enough (actually, more than enough) to boil the oceans away…which makes me wonder how the water managed to stay on the surface for a year.

Also, you keep arguing for the ability to build mountains despite high erosion rates but forget that mountains are still eroding even while they are gaining altitude. It is just that they are being uplifted faster than they are being eroded.

–Uhhh, I never forgot that. In fact, I could have mentioned earlier that there is some evidence that even the erosion itself may be helping them grow. (Link: http://www.sciencedaily.com/releases/2003/08/030807075917.htm )

@Professor Kent,

I’m disappointed, but not surprised, that Dr. Pitman chose to ignore this problem. According to Pitman, plate tectonics moved very rapidly during the flood and then slowed down, which creates the dilemma Kris has spoken to. The massive ocean basin and its seamounts could not have existed prior to the flood, but how could they possibly have formed in such little time during the flood itself–or during the following year?

In my judgement, it was the strongest point I made in that comment.

@ Professor Kent

How bizarre that I argue for the superiority of the Bible, and Bob, rather than joining me, says that Richard Dawkins–of all people, being one of the most antagonistic toward the Bible–is on my side! WHO ARE THESE PEOPLE THAT CLAIM TO DEFEND SEVENTH-DAY ADVENTISM?

The way some of out fellow christians associate others with positions they just do not like with “hard” atheists like Richard Dawkins is nothing more than an ad hominem. — In a different thread on a different website, one person I was talking to kept bringing up Richard Dawkins. It was “Richard Dawkins says..” “Richard Dawkins claims…” It was all a tactic to simply dismiss what I was saying simply because he thought Dawkins would agree with me…even slightly. But there are major problems with such tactics: 1) Richard Dawkins speaks for Richard Dawkins, not for me. 2) I don’t even care what Richard Dawkins says, and our fellow Christians who worry about what he says should have better things to worry about. There seems to be a mentality here that because Dawkins takes a certain position, that we should take the opposite extreme, but that doesn’t even follow.

Let the hard atheists like Richard Dawkins, Daniel Dennet and Christopher Hitchens say what they want…It makes no difference to me.


Panda’s Thumb: ‘SDAs are split over evolution’
@Sean Pitman,

You said before that overall rate of erosion and and sedimentation world wide along with the replacement of the materials is constant… I know that. But you keep assuming that the rate of today is the same as 200 million years ago, and quite frankly, you have no basis for such an assumption…and really, there is reason to believe otherwise as well.

Geologists point out that the landmasses of today are much more mountainous and more rugged than in the past….and the mountanous topography is a excelerator to the rates of erosion…Now, if this is true, then that would mean that today the overall rate of erosion (and the addition of sediments to the ocean basins) would right now be at an all time high…As such, the current rate of sedimentary deposition cannot be used as a reliable clock to date the ocean floor. (Davis Young, Christianity & The Age Of The Earth, pages 128-131)

Reputable Creation Scientists give vastly different estimates of the sea floor accumulation. You give the estimate of 15 million years. — Henry Morris gives the estimate of 75 million years (Scientific Creationism, pages 155, 156) — Stewart E. Nevins gives the estimate of 30 million years (Link: http://www.icr.org/article/evolution-ocean-says-no/ ) — Russel Humphries’ estimate is 12 million years (Link: http://creation.com/evidence-for-a-young-world ) — With all these vastly differing estimates on the parts of creation scientists, it makes me wonder about the basis of their data…especially since it’s the same argument. It’s not as if we have numerous dating methods being used and all disagreeing…Rather, it’s that we seem to have the same method being used and still disagreeing.

–But I think I’ve found the mentality behind your argument. Stewart Nevins, on his page about the sedimentation of the sea floor, says:

In only 30 million years assuming constant rate of erosion all the ocean sediments could have accumulated. This age does not square with the over 1 billion year age assumed by evolutionary uniformitarian geologists. (Bold, his)

So, his argument is that since today’s rate would have deposited more, that therefore the principal of uniformity is wrong.. I dare say anyone who claims that geologists think “rates” have always been the same for EVERYTHING doesn’t understand the principle…At least, not in it’s current form. The principle he is refering to is known as “Substantive Uniformitarianism,” and modern geology rejects that. — Geologists now use a different principle called “Methodological Uniformitarianism”; that is processes around today have happened in the past…whether it be a storm, a mudslide, a volcanic eruption, etcetera..They may happen at different rates, but the same phenomena that happen today leave a finger print, and we can identify a geologic formation from the past with a similar finger print.

Scientists ‘potentially skeptical’ of evolution need not apply
I do not know all the details, but I do think that the University is handling this situation quite badly. In the actual news article itself drom the Hufington post, some scientists are quoted as saying that they may as well have a “Creation Museum” with him around… Logical Fallacy: “Slippery Slope.”

@Sean Pitman,

At the very least, global migration under ideal conditions, even of sloths, seems plausible (and I think unavoidable given the doubling time for sloth populations under ideal circumstances) – certainly not “impossible” as you’re trying to suggest.

Well, for the record, I said “it would have been difficult, if not impossible.” Perhaps it was possible.

After all, even sloths can move up to a mile in less than four hours when they want to…

They can move faster under some conditions. But it is my understanding that even though they could, they tend not to. They tend to pick up the pace only when necessary; like when they are fleeing from a predator, they can move up to 15 feet a minute, and even then they burn a lot of energy while doing it. On the grund, their maximum speed, however, is 5 feet a minute. (Link: http://www.animalcorner.co.uk/rainforests/sloth.html )

— Perhaps a journey of such a route could have been possible under certain conditions. Who knows?

But, what I am more concerned about is not the journey, but rather a trail that they would have left behind from Eastern Turkey to North America. I’m more interested in what they would have left behind on their migration to indicate that they were there. For a while, they should have at least had a population in those regions… Perhaps they still would have decendants in Russian forests, or skeletal remains from those who did not make it.

@Professor Kent

Thus, we cannot expect each successive generation to continue a straight-line march across the globe for thousands or even hundreds of years. In their normal daily movements, they might move 5 miles in a year…but not in a straight line. We have been reassured that even a “small slow tree sloth” can migrate at a 12-mile-per-year pace across the globe. I don’t think so!

It would require movement in areas of the world that they are not adapted to. It would have been difficult, if not impossible, for the sloth to move from Eastern Turkey, across the Bering Straight land bridge, then from Alaska and then to South America…But, for a moment, lets suppose for a moment that they succeeded…

The sloths tend to live between 10 and 20 years, and in that time they tend to have a single newborn per year. If we go with the conservative number that would mean that at minimum, they probably reproduce 10 newborns within 10 years, but it is also true that the newborns tend to have a high mortality rate within the very first year of their lives. – There is no statistic at the actual death rate in the first year before they have a chance to reproduce, but since there obviously was a net gain in the population (since the flood), that allows the minimum survival rate to be 40%. This would mean that if they birthed 10 newborn sloths, then a maximum of 6 die. If 2 males and two females survived, and if they in turn also had 2 males and 2 females that survived, there would constantly be a doubled population of sloths: The first generation (from the ark) which would be 2 sloths would therefore lead to 4 which in turn leads to 8, and then to 16, and so on and so forth.

[The mistake I made in a former comment was allowing the survival rate being 20% which, now that I think of it, would have only produced only two surviving sloths constantly. It had to have been more.]

Add into the equation that it is over 3,000 miles from Eastern Turkey to the Bering Strait which leads to North America. – Using Sean’s estimate that they may have traveled 12 miles in a [year], that would indicate that they made it to the outskirts of North America in 250 years. With this in mind, one is left to wonder about a population of sloths in modern Russia which should have been considerable…or at least noticeable, though it is possible there may have been times when their birth rates and survival rates would have dropped a bit, though that doesn’t clear the problem, and there should be evidence of such a migration from Eastern Turkey. – Also, when one factors in the time sloths spend sleeping in a day (15 to 18 hours a day), the idea that they could have traveled 12 miles a year is a stretch. And that goes without mentioning that they almost never get out of the trees. That begs the question of how far they were willing to walk over treeless territory until they would find more trees.


Why those who hate the Bible love blind-faith Christians
In my experience, those who hate the Bible hate any kind of Christian, not just people of blind faith.

But I don’t think anyone here is really insisting on blind faith, I think they just don’t want to use a certain sort of “test tube” for God. –There is evidence that the Bible is divinely inspired, which is why I hold it in high esteem. Even in the areas that would seem to have some “weakness” of archeological evidence, there is still some real strength that warrents belief. The profecy of the “cutting-off” of the messiah in Daniel 9:24-27 actually gives a time-frame that Jesus really seems to match, and as such I see true divine inspiration in the book of Daniel (which is actually my favorite book of the Bible). Even if Daniel were written in 164 BC, as a lot of skeptics believe, no uninspires writter would ever know such a detail. So, despite my differences of opinion of interpretation, there is no doubt in my mind that God did in fact inspire the Bible. This itself, in my judgement, is good, imperical evidence for not just the Bible, but also God himself.

But, as said before, the problem others here have is reducing God to a “test tube.” As a Christian myself, I am not crazy about that. — You ended your post with a good quote from Galileo Galilei, and so I shall end this comment with another from him:

The Bible teaches how to go to heaven, not how the heavens go.
