Luckily the age of the earth does not need your approval
The Isua Greenstone Belt stone is 3.7 to 3.8 billion years old
The Zircon in Jack Hills is 4.4 billion years ± 6 million years old.
Perhaps if you learned a little about dating methods rather than dismissing them out of hand because they contradict your belief... You may learn how accurate they are and what the error margin is of each method. You will note the ± 6 million years for the Jack Hills Zircon, its the error margin.
Where possible more then one method is used to verify the result and they are indipendentely checked. So "unfounded" is way out of the ballpark.
prove that those stones are that old
a 4 billion year old rock is impossible. if an unstable heavy element decays at a specific rate it doesnt mean that it always decayed at that rate and it is not logical to assume that the daughter elements found in a sample are all the consequence of the decay of the parent element.
if a glass of ice melts at a certain rate when the room is at a certain temperature can you reliably judge how long it was since the glass came out of the freezer? maybe not all the water was frozen to begin with, maybe the temperature of the room wasn't constant and how long was the glass in the freezer to begin with.
im not smarter than you, im sure that what i say is perfectly rational.
i guess we all have a job to do for someone.
