Note to Brian:
In skeptoid episode 142, you answer a question about radiometric dating, "Is carbon dating inaccurate?"
You cover carbon , potassium-argon, and few other types well, but you don't mention uranium-lead dating. This is a little disappointing because the oldest earth rocks have been dated with uranium-lead dating, which has dated rocks as old as 4.6 billion years. It is uranium-lead dates which are used to estimate the age of the earth, which may be relevant to the argument-with-a-creationist context of the question.
