Pariah, you're simply wrong on this point. Ask any astronomer, chemist, or geologist. Radiometric dating has an upper effectiveness limit, yes--but the 50,000 year mark applies only to organic material, not inorganic ones.

You're thinking of CARBON DATING, which is a (relatively) short-term isotope and is less accurate at its upper range of 50,000 years or so. URANIUM-LEAD dating, which works with much longer-lived isotopes, operates in the range of hundreds of millions of years.

Unless you think the U.S. Geological Survey is in on the conspiracy, you'll have to give this one up.
