Couldn't let this one go.

Radiometric dating is good for about 14. 6 billion years depending on which isotope is used to date.
I don't know where you got your information and since you didn't offer any proof source. I will bring up what I have found.
Radiocarbon dating was invented by Willard Libby at the University of Chicago. Willard Libby said that carbon dating was only accurate for OBJECTS A FEW THOUSAND YEARS OLD.
Interesting you stated 50,000 years, the inventor said about 2000. Who should I believe?
Living penguins have been carbon dated as being 8000 years old.
There are flaws in the c14 dating methods. 1. The atmospheric c14 is in equilibrium. This assmuption is wrong. The amount of c14 in the atmoshpere is still increasing. 2. The decay rate remains constant. This assumption is also untrue, the decay rate may not be constant. 3. The initial amounts of c14 can be known. Again this assumption has been demonstrated to be wrong. Different parts of the same sample often yeild different ratios. 4. The sample being tested has not been contaminated for thousands of years. This assumption is mostly impossible to prove. Parent or daughter products may have leached in or out of the sample. Lab tests have confirmed that this can happen.
Radiometric dating; you stated 14. 6 Billion years. Interesting, since you claim that the earth is 4 Billion years. Is there something else that's 10. 6 Billion years older that has been tested? Obviously, it couldn't be from this planet.
Which Isotope to use (radiometric dating)??????? The two most popular methods are uranium-lead and potassium-argon.
At least six different radiometric dating methods are available. The ASSUMED age of the sample will dictate which dating method is used because each will give a DIFFERENT RESULT.
Since these methods have been believed and touted as the best dating techniques, there has been experimentation to verify these claims. Example: Hawaiian lava flows, which are known to be less than 200 years old, have been dated by the potassium-argon method at up to 3 billion years old.
Example: when dinosaur bones containing carbon are found, they are not carbon dated because the result would be only a few thousand years. Because this would not match the assumed age based on the geologic column, scientists use another method of dating to give an age closer to the desired result. All radio-metric results that do not match the PREASSIGNED ages of the geologic column are discarded. (circular reasoning)
It's a religion, a system of beliefs.
