I hate to rain on the parade but ... Everything on Earth is the same initial age.

Irrelevant! Are you on Earth? Are you 4.2 billion years old?

Here are some folks posing with 420,000 year old ice cores they drilled out of the 12,000-foot thick Antarctic ice cap.

Why would you freeze your ass off digging up ancient ice? Because it contains tiny bubbles of air, preserved as they were the day they were trapped. That air has been separated from the rest of Earth's air since it was trapped (how long ago depends on how far down). It's interesting to pass it through a mass spectrometer and compare the results to today's randomly mixed air. There is no other way to get such information.

All I said was that the ELEMENTS are all the same age. Compounds come and go. The ice core compounds have been stable for a long time. So what? The ELEMENTS that structure the compounds are all the same age. Compounds come and go. Elements are all the same age.

In a manner, yes. I am made up of compounds structured by elements. The elements are all the same age. The compounds that form me are much newer.
