The thing is the creation scientists don't really have any radiometric dating that proves their point.
Noah's flood and other catastrophe comes up as one reason why they can't extrapolate backwards and would make dating inaccurate.
The problem for creation science is they've also dated lunar rock samples to similar ages and there was no noah's flood on the moon as far as we know.
When you date the earth, and get a figure of millions of years...and then date the moon and get the same figure..that says something pretty clear about the age of the earth and accuracy of the dating methods.
Scientists don't only use radiometric dating they have other methods too of course. Radiometric dating wasn't the first technique to give old earth ages. In the 1700's rate of cooling experiments gave figures of 75000 years. In the same period studying layers of rock etc gave figures of millions of years. Studies in the 1800's of the rate of change of cooling assuming the earth was molten, gave millions of years, as did time calculations on the affect of tidal friction. But it's pretty hard to argue against radiometric dating which uses known half lives of different elements. But I always consider this type of science 'pseudo-science' because we can't go back into the past. I attribute the age of the earth as calculated by dating methods to old dirt, and still believe in a literal 7 day 6000 year ago creation. In other words, science is correct when they date the earth's substance to be billions of years old, but they don't accept that it was created 6000 years ago.
