I've always wondered this...if God is omniscient and if He was pleased with all He had made at the point of Genesis 1:31, why would He have created things just to have them change...or evolve?

Would an omniscient God not create HIS own creation completely, with no need for evolvement or change?


I would interpret that to mean that God finds change good. This is a point at which the biblical conception of God differs from the Platonic conception that was so prevalent during the early Christian era and from which the church borrowed a lot more than it should have.

For Greeks, like Plato and Aristotle, perfection was static. The motion which marks the world we see was interpreted as an effort to come to a state of perfection in which something could rest. And, of course, this also involved theorizing as to why things had fallen away from perfection in the first place.

The "God" of this belief is not recognizable in Yahweh, the God of the bible. It is an "it" not a person. An Absolute that is unaware of anything but itself. All things are drawn to its perfection and stillness, without it being even aware of them. For such a god there is no activity, no longing or desire, no history, no emotion or passion of any sort.

By contrast, the God of the bible is characterized by dynamic activity, by emotions such as love, mercy, anger and righteous indignation. This God is personal and in your face. This is a God that is fully aware of you and makes demands on you. And this is a God that is active in history.

A dynamic creation seems IMO to be very suited to a dynamic God. Why would such a God find a static perfection in which nothing ever happens "good"?


How do you reconcile that to Hebrews 13:8 and Hebrews 1:2? We are shown, over and over in the Bible, that God is unchangeable. If we cannot rely on the absolute immutability of God, what hope do we have??? If we think He is a God that has allowed His creation to evolve, when he at one time declared it "good", how can we have a sure hope of anything at all? How can we be sure that the price Jesus paid for our redemption will continue to be good enough, regardless of how bad we become? How can we even know there is absolute Truth?

I'm just not seeing any biblical precedent for the God you describe. It paints God as being "relativistic".

No, it paints God as not reveling in stagnation. While God may not change, that doesn't mean He can't change his tactics or be swayed via petition. Abraham repeatedly asked God to change the criteria under which he'd save Sodom & Gomorrah and God agreed. The system of worship he set up in the OT is drastically different than the one in the NT. What's the point of prayer if everything is predetermined?

No, we can do better than guess. As Yamaguchi clearly knew, since he was pointing out one solution to reconcile the problem of cross-correlation artifacts. When he used ARIMA models to improve the matching, "A single bark date - AD 1647 - was found to have a t value significant at the 0.001 level." No need for guessing when you have 1 possibility.


I'm not sure whether you're reading the statistical results correctly. The p-values were all at the 0.001 level for all 113 matches.


Only when using the method that Yamaguchi was calling attention to as a potentially "suspect" method. When using his suggested ARIMA algorithm, there was only one match at p=0.001.

Agreed, but the deeper strata have a different isotopic ratio than shallower strata, and this top to bottom gradation shows a consistent gradient in isotopic ratio. An omnipotent creator can do as he/she likes, of course, but this hypothetical YE creationist has to accept this 'pseudo-appearance' of age as either a grand coincidence or a deliberate design element.

Mmm, sometimes. Not always. For instance, in the Grand Canyon, Rb/Sr measurements showed the Uinkaret lava flows (~1.3 billion years) to be older than the Cardenas basalts (~1.0 billion years), despite the fact that the Uinkaret flows extrude at the top of the Grand Canyon with some flows going down into the canyon, while the Cardenas basalts are beneath all the stratigraphic layers at the bottom.


Again, Dr. Austin's conclusions are disputed by other geologists:

quote:

"Summary
The ICR's Grand Canyon Dating Project does not strike a telling blow against the reliability of isochron dating. The conditions which caused the "false isochron" in this case are fairly well-understood, and easy to avoid by proper sample selection. In fact, the resulting age in this case may well be meaningful and accurate. The problem is not the age itself but rather Austin's sleight-of-hand in trying to pass off the result as necessarily the age of the flows rather than a minimum age of their source.

The attempt to abuse the meaning of a single contrived date -- which was produced only by a sample selection geared to dating a different event, and only for samples whose results were known by Austin in advance -- says a lot more about the level of competence or honesty in this creation "science" research program, than it says about the validity of isochron dating methods.

Even if given credit for discovering this case (which he clearly doesn't deserve, as his use of Leeman's data proves), Austin has only managed to "call into question" a particular sampling technique. However, this sampling technique was known by mainstream geologists to behave in this manner long before Austin published on the topic, and this behavior is often intentionally used by geologists. Austin was aware of this, as his 1988 reference to Faure shows."

I found your answer to mushhead interesting. While I agree that it will be difficult to get an accurate reading using such a large-scale "ruler", I would point out that we haven't exactly had the luxury of checking that "ruler" against anything that can be unequivocally dated as 2 million years old or older...


There does seem to be a lot of skepticism hereabouts, so I made no dogmatic statements, and I explicitly admitted that we had no simple dating methods against which we can check K-Ar dating. Nevertheless, radiocarbon gets us out to 10,000 years with dendrochronology with good linearity. And varves takes it out to 40,000 with okay linearity. If there's even lousy uniformity with potassium-argon dating, so that it's off by a factor of 1000, that still provides earth ages in the millions of years. So even with error bars 100 times bigger than I think they are, these methods disprove naive Ussheroid chronologies by a factor of 1000 or so.

Given the extreme differences between the new covenant and the old covenant I don't see how Christianity can possibly view God as unchanging.

Gnostics even went so far as to say the old testament God was an evil deciebtful deity, and that Christ was the salvation from this evil God. According to Christianity (and most other religions) God can be influenced and convinced to deviate from his perfect plan through prayer. How can a Christian believe in an unchanging God?

God tells us to pray...that's why we do it. There is biblical precedent for God allowing man to intercede via prayer...Moses, Abraham, etc. God's truth and justice still prevailed in those situations. God cannot be swayed! Again, if He was not immutable, we would have no hope. God is the only "thing" that can truly be called unchangeable.

There is no biblical precedent for God being changeable...in fact, we're told the very opposite in scripture. We don't want to serve a God that can be swayed or is given to change!

And before a moderator tells us this is off topic...I really don't think it is. My point is, when God said His creation "was good", then it was...and it didn't need to be "tweaked".

Well, of course they are. Like I said, what needs to happen is large-scale multi-sample testing using all the tests. Let's stop fooling around and figure out what the actual accuracy of these things are, instead of continuing to make wild guesses and expect everyone to buy it.

Varves is a mess, as previously discussed. Nor is it terribly surprising that decay rates would match for a period of time roughly approximate to the YE expectation of the age of the planet, for the 10,000 year statement.

10,000 is also kind of not impressive compared to, say, billions. The extrapolation is scientifically unsound. Not to mention that the processes involved in C14 accumulation and dating are completely different from the processes involved in the other forms.

You can't say "well, this ruler here looks like it works for the first 3 inches, so I'm betting that tape measure over there is accurate to the full 240 feet!"

So prayer is useless then? Unless prayer is nothing more than self conciliation, God has to be sway-able, or changeable.

I think we have to ask in what respect God is unchangeable. I would say that the character and purpose of God does not change. God's loving-kindness and faithfulness do not change. However, how he expresses these things can change.

quote:

If we cannot rely on the absolute immutability of God, what hope do we have???


As others have pointed out, I think our hope is based both on the immutability of God's nature and purpose and his readiness to change tactics. If God were immutable in all respects, Lot and his family would have died in Sodom, for nothing Abraham said could have changed his intent. Or the Israelites would have been destroyed in the desert, whereas Moses' plea for mercy saved them. Or, Noah would never have needed to build an ark because God would never have repented of making humans and never sent a flood.

A God who acts in history necessarily changes history and we must accept that these changes are in accord with his unchangeable purpose. A God who answers prayer can adapt his methods even though he is unchangeable in the love than makes him receptive to prayer.

When God knowingly made a universe that was thermodynamically active, he must have done so in the foreknowledge that this would be a universe with a natural history of change. And that must be one of the aspects of his creation that he calls "good".

quote:

If we think He is a God that has allowed His creation to evolve, when he at one time declared it "good", how can we have a sure hope of anything at all?


I don't see the problem. If God made life to evolve, then its subsequent evolution is part of his good purpose. Evolvability is a good characteristic for life to have. How has it deviated then from what he originally called "good"?

Oh, and just a final note. Let us not confuse God making changes with God himself changing. An unchanging God can still make a changeable world and call it good. An active God may still be single-minded and true to one unchanging purpose.

'Good' only with the method that Yamaguchi is calling into question and attempting to improve. Middle of p.51, using his preferred method: "A single bark date - AD 1647 - was found to have a t value significant at the t = 0.001 level" - the same thing I quoted in post #44.

That's right, uranium and potassium based methods are unaffected by the atmospheric changes that make radiocarbon dating somewhat more complicated.

The first 3 inches of radiocarbon dating already disprove an Ussherian age of the Earth. The other tape measure, based on similar assumptions to radiocarbon dating, even if wrong by a factor of 1000, still yields ages that disprove an Ussherian age by a factor of 1000. There is a factor of 1,000,000 between radiometric ages and YE ages. The actual experimental data shows a change consistent with 0% change in decay rates over the past century. For the sake of argument, I'm willing to grant an error of 100,000%, and this still disproves YEC by an enormous margin. The actual error appears to be less than 10%.

This is getting off topic, so I'd better be going before I get slapped around! (Because, there's nothing, this side of heaven, that will change my belief about the age of the earth.) As for the prayer issue...how did Jesus pray? What were His prayers like? Those should be our examples.

I'm off to look for a thread on "Why and how we should pray."

I find it interesting that they fail to show the t-value residual charts or numbers for the ARIMA method. As such, we can't tell whether or not anything else is close, we just have their word on it. You would think that if it's the slam-dunk they say it is, they would want to display the improvement comparison. Instead, they appear to be displaying a per-ring ARIMA residual mapping assuming that 1647 is the bark death year, which frankly is rather messy in spots.

Problem being, again, that to a young earther, the uranium and potassium methods are too large-scale to be at all useful and correlate to natural rock values when the rocks were popped into being.

Of course there's a 0% change in decay rates. Decay rates are basically constant given a closed system. I've never argued that point. The question is whether or not environmental injection rates are constant, which requires atmospheric equilibrium, which demonstrably does not happen. And, whether or not there is contamination, which testing seems to indicate is rather common.

I think the problem with attempting to scientifically discuss the potential for interference by a supreme being is the fact that it's basically an untestable case. A supreme being could have popped the entire universe into being, in its present state, 5 seconds ago, with everything intact, and we wouldn't know any different. Which, frankly, is why I'm fairly apathetic on the matter (despite a certain level of amusement when it comes to playing devil's advocate on it) and am quite comfortable in saying "well, if you're going to invoke interference by a supreme being, we simply cannot know." I am just as okay with the idea that the earth is billions of years old as I am okay with the idea that, given omnipotent interference, the earth could be five seconds old (or 6,000 years old). Unfortunately for you, I am somewhat bored and procrastinating on learning Silverlight at the moment, and I have a mild allergic reaction to tests that are so terribly sloppy as they treat radioisotopic testing. They need to get their acts together, do some double blinds, and do some comparitive testing on some of the rather lovely strata we have available. Then let us know whether their tests are accurate, or whether they need to get their acts together and find something else.

I do not necessarily hold to the view in question, however, the answer to this question is obvious if you look around you. A tree begins as a seed. You and I began as zygotes and then infants. There is nothing inherently imperfect in designing change and growth into the system.

Therefore, IF God saw some reason to create through evolution, this does not indicate faulty planning in His part.

Atmospheric changes only really affect radiocarbon dating (which is why the calibration curves are so helpful in improving the method). No lead or uranium is transpiring into or out of rocks. As you mentioned before, lead may come out of melted zircons, and your point about contamination is very true. Nevertheless, the factor of a million difference between radiometric ages and Ussheroid ages can't really be swept under the rug with these minor quibbles about the method.
It can only be swept away with a major quibble, such as your example of an omnipotent deity popping the universe into existence 5 seconds ago with the isotopic ratios as they are. In this case, radiometric dating would be worthless (although we could never discover that fact, since the omnipotent deity made the universe in such a way that suggests a great age).

I don't know of any for geological samples, but the dating of the Shroud of Turin was double-blinded and carried out by 3 independent laboratories, and they included three control samples: medieval cloth, Nubian linen, and Egyptian mummy wrappings. The measurements weren't identical, but showed pretty good agreement between the 3 labs, and between the measurements and the more-or-less known historical ages of the control samples.

Atmospheric changes only really affect radiocarbon dating (which is why the calibration curves are so helpful in improving the method). No lead or uranium is transpiring into or out of rocks. As you mentioned before, lead may come out of melted zircons, and your point about contamination is very true. Nevertheless, the factor of a million difference between radiometric ages and Ussheroid ages can't really be swept under the rug with these minor quibbles about the method.

Right, but since we can't short-term test the long-term radioisotopic stuff, it's basically impossible to verify. The time scale differences are just impossible to rectify. Just by saying that the long-term radioisotopic tests are even performable, you have already entirely discounted any possibility whatsoever of YE theory being correct, because the time scales involved are just that different.

That's like saying "There might be germs on the surface of this table... let's get out a telescope and check."

It can only be swept away with a major quibble, such as your example of an omnipotent deity popping the universe into existence 5 seconds ago with the isotopic ratios as they are. In this case, radiometric dating would be worthless (although we could never discover that fact, since the omnipotent deity made the universe in such a way that suggests a great age).

Or had other reasons for doing so, or we're just misunderstanding the data.

I mean, we just finally figured out what the appendix is for last year.

It would have been more valid if they had reduced the samples to carbon dust prior, as it was apparently evident which sample was what from what I hear. But, it's a good start. :)

Even for isotopes with half lives in the millions of years you can still measure thousands of decays in a matter of minutes with a large enough sample. One must remember that there are 6.022 x 10^23 (short hand 6.022E23 for future reference) atoms per mole (Avogadro's number). Just for fun, let's do the math.

For 40K the halflife is 1.25E9, or 1.25 billion years. In that time half a mole will decay for 3.011E23 decay events. For one mole of 40K that calculates to 2.4088E14 events per year. Dividing by 365 days that is 6.6E11 events per day, 2.75E10 events per hour, and 4.58E8 events per minute. That's 458 million events per minute from one mole of 40K which is 40 grams. From 40 milligrams one would get 458,000 events per minute. This is just back of the envelope math, so please check it. Also, I am sure one needs to run a differential to get the actual count, but it is still possible to get quite a few events from a small amount.

Nature has already done those experiments. One example is the naturally occuring nuclear reactors at Oklo in Gabon, Africa. If the radioactive decay was the same in the past as it is now then these nuclear reactors should have specific ratios of byproducts of that decay. That is exactly what is found. Also, astronomers were able to measure the production and decay of cobolt isotopes in Supernova 1987a which is 168,000 miles away. The energy and half life of these isotopes are the same as they are here on Earth 168,000 years later.

For atmospheric fluctuations of 14C the tree ring, varve, coral doublet U/Th dating, ice layer data all give historical concentrations of 14C and cross correlate across many different continents and environments. The actual age and measured age can be matched up due to the annual characteristics of these data sets.

The other problem with zircons being formed with lead already in them is that zircons can be found in sediment that overlay fossils. This means that these zircons were formed after life was already present on Earth. These can not be zircons that were formed at the time of creation, that is unless the Earth was created with fossils already in the ground which would cause some serious theological problems (one would think). So creationists must explain why there is a correlation between two independent and unrelated data sets: the ordering of fossils and the concentration of lead in zircons. For instance, how does a flood sort fossils so that they are only found in layers with zircons that have a specific ration of Uranium to Lead.

We have known what the appendix does for quite some time now. The appendix is a part of the caecum which houses commensal plant digesting bacteria in herbivorous species. In humans the appendix serves a rudimentary and vestigial role.

This is indeed the scientific position.

As previously noted, I'm entirely aware of how radioactive decay works (including on the quantum level, as my college education required me to take a course in quantum physics, which is a hoot). I have never argued the ability to determine rate of radioactive decay. I have, however, questioned our ability to properly guess the original ratios of parent to daughter element, and our ability to determine the potential for contamination.

I've already addressed a few of those, but as I need to get ready to go work on our house in the mountains again this weekend, I will reiterate the short version: When you assume a divine creation event in which everything pops into being fully formed and functional, it could happen 5 seconds ago, 6,000 years ago, or several billion years ago and there wouldn't be any measureable difference. "Why's this like this?" is invariably answered by "Because God made it that way." Not exactly something one can argue given the base assumption of an all-powerful supernatural being.

Which frankly is one thing that kind of drives me nuts about some "creation scientists". You can't scientifically prove a supernatural creation event. It's simply not possible. You can point out little quirks in what "should have" happened and say they're cool or mess with prevailing theory or what have you, but scientifically proving divine intervention is like Star Trek geeks trying to prove that the transporter really works (It apparently uses a Heisenberg Compensator. How does it work? Very well, thank you.) Not to make light of our faith by comparing it to a television show (even if it WAS one of the best television shows EVER), but the point is... when you're talking about a creative being able to make stuff out of "nothing", all bets are off.

Mmm, zircon overlays can be formed like that, or they can simply be part of the sedimentation from upstream erosion of parent rock. Or the initial estimates of starting parent-daughter ratios could be off. Frankly, hard to tell. Since we haven't had a worldwide flood lately (good thing), also hard to model.

Not according to Duke scientists. http://www.news-medical.net/?id=30907 While you can certainly live without one (especially if you know how to reflorinate your digestive tract), it's like your pinky... not critical to life, but not vestigial either (at least if you want to be able to press "enter"). ;)

As it pretty much has to be, since supernatural intervention in creating life, the universe, and everything, is an unproveable quantity, scientifically speaking. *shrug*

Which is why I'm in the "well, we can't really know" camp. When you believe in an all-powerful being, anything can happen. Quite literally.

But that's exactly what evolutionists refuse to admit. There seems to be so much pride leading to an attempt to explain everything in human terms. If we can manage that, we can deny God's authority and omnipotence and bring Him down to our level.

It's much easier to keep things on our level by discussing zircons, isotopes, halflifes, decay rates, double blind studies...makes us feel like we're in control by dealing with things we can control.

Plenty of people who accept evolution believe in an all-powerful being.
