CHISTIANS PLEASE EXPLAIN

[pocaracas]

What assumptions are they using? The same ones that concluded that the rocks from Mt Ngauruhoe was dated into the millions of years whereas it was only a few years?

Don't you think it's interesting to note that if you search for "Mt Ngauruhoe rock dating", the first 12 hits give you creationist related sites, then the 13th is the wikipedia entry and then back to creationist sites...?
Now why is that?
Why isn't that particular piece of information available from reputable sources?
And those creationist sources all revolve around one particular dating method, the Potassium-Argon (K-Ar).
Now, bear in mind that these sites are claiming that the use of this method to dating lava flows from the 1950's yielded wrong results.

Now look at the applicability of this method (from wiki the layman version, as you like it):

Due to the long half-life, the technique is most applicable for dating minerals and rocks more than 100,000 years old. For shorter timescales, it is likely that not enough Argon 40 will have had time to accumulate in order to be accurately measurable.

So, measuring 50 year old rock with a method that can only give you reliable results for rocks older than 100,000 years... huh? clever chap, whoever thought of wasting resources with that measurement... -.-'

Now, tell me why you brought up a flawed measurement, when it was stupidly applied to a piece of rock known to be grossly outside of the method's domain of applicability.
While you're at it, tell me why there are so many creationist sites propagating this stupidity.
