He basically said, that of the 80 or so methods of determining the age of the earth, scientists pick only those that give them the ages they are look for, and reject all the others that return a young earth age.
Any proof of that? Or does he also include rejecting
bad science? If someone does an experiment and screws it up badly and hamfistedly misinterprets data and abuses results and how the instrumentation works, and the rest of science rejects it,
it doesn't mean the scientists are biased.
He said there are four methods that scientists use:
- Argon [something]*
Good start: "argon something". Please don't insult our intelligence. If your pastor is so brilliant at this and you are his mouth on this board, do a better job than "argon something".
- Potassium [something]*
- Uranium [something]*
- Krypton [something]*
Actually most of us who have training in this actually
do know the names for these. There are a number of each of these. Would you like a list? (I don't even know your pastor so here you go):
40Ar/39Ar dating
K/Ar dating
U/Pb dating
U/Th dating
There's some methods that use 85-Kr to date groundwater. I'm not that familiar with the other uses of 85-Kr. They used to use 85-Kr also as a tracer in some aspects of oceanography (at least there were some 85Kr tanks sitting around the labs I occasionally worked in when I was in oceanography, but that wasn't my area).
Are there "critiques" of these methods? Yes! But if you look in the "young earth literature" most of what I've read amount to abuses of the techniques and misuses of the techniques. Poor technique, bad methods and general sloppiness.
If you'd like to discuss some at length I can probably point you to one of many, many such discussions which are on this very forum itself.
He went on to say that the other 76-some are rejected for one reason or another:
- moondust
Then your pastor would be interested to see what the braintrust at ANSWERS IN GENESIS says about the moondust hypothesis:
(Remember
these are CREATIONISTS saying this!)
It thus appears that the amount of meteoritic dust and meteorite debris in the lunar regolith and surface dust layer, even taking into account the postulated early intense meteorite and meteoritic dust bombardment, does not contradict the evolutionists multi-billion year timescale (while not proving it). Unfortunately, attempted counter-responses by creationists have so far failed because of spurious arguments or faulty calculations. Thus, until new evidence is forthcoming, creationists should not continue to use the dust on the moon as evidence against an old age for the moon and the solar system.(

- strength of the earth's magnetic field
Again some training in actual science might serve your pastor well. The earth's magnetic field has altered and fluctated and even reversed numerous times in geologic history. It was relatively constant from 1590 to about 1840 and the recent alteration may be another one of these fluctuations. (

- ocean salinity
- a bunch of others
* He gave the exact names, but I can't remember them.
If Dr. Morris had been keeping track of Aluminum apparently it would show an age of the earth of about 100 years. The numbers that Morris sites for various elements dissolved in sea water are
residence times. Elements can come and go into the system through a variety of means.
As for the "bunch of others", well, considering that the ones you listed are essentially PRATTS and one is outright
disavowed by young earthers, I'd say "trust but verify".
I think the book A Case for a Creator, by Lee Strobel mentions them all as well, weatherman.
Oh wow. You know I have much respect for someone who got a Journalism degree at a school where I worked at the J School's paper briefly, but sorry, I'm not going to toss all the geology I learned in favor of Lee's "list".
