How old is the Earth?

Not really what I am saying. Decay rates have changed, we know this because different isochronic methods of dating yield different dates for the same rock. If decay rates were always constant each isochron should yield the same age, they don't. The biggest factor that would skew radiometric dating would be the presence of daughter elements at the time of Creation. This is why radiometric dating cannot be used to "disprove" a young Earth, it assumes something that would not be true if the Earth was young. Try and date a person (using their height and weight) using the same assumptions radio-metric dating uses and I guarantee your conclusion will be way off. Thanks for being civil though, makes thing way more fun I think.

No, decay rates have not changed. There is no evidence whatsoever that they have. Thousands of laboratories the world over use radioactive dating of material samples, and have done so for decades with huge success. If you have proof that they are wasting their time and money, you should publish your peer reviewed paper pronto, so these labs won't wate their money on bogus science. Good luck with that.

I noticed you just made an assertion and didn't address my argument. Typical. If decay rates are constant then why do different isocrons yield different ages on the same rock? Is that rock really three different ages at the same time? Geologists are well aware of this problem, they just throw out the younger ages and keep the oldest one becuase it fits their pre-conceived ideas. Why do you think you have to identify which layer of strata a sample was collected from when you send it to the lab? So they can throw out the dates that don't match! Simple stuff.

Archilies heel fallacy, you claim knowledge of examples that are contrary to the expected outcome but provide no examples. What have you got in your bag of tricks here, a silly example about a snail dating to 25,000 years or other examples of creationist mucking of the actual results?

Decay rates have not changed, and the vast majority of experiments have confirmed this. Can you explain why the vast majority of results should be ignored?

Different isochrons yielding different ages for the same rock is a common occurance. The final age is determined by which layer of Strata the sample was found in. This is basic basic stuff here. Decay rates have changed, everyone knows that.
