Those are not predictions. Those are estimates. If you will take the time (no conscious pun intended) to investigate the nature of those updates over the past couple of hundred years you will discover the following:
- The early estimates of age were , compared with the current ones, quite small - tens, or hundred of millions of years
- There were large error bars attached to those ages
- As technology and understanding increased the age estimates grew and the error bars shrank
- For around half a century the age has been estimated at approximately 4.5 billion years.
- Changes in this interval have been refinements of tens of millions, then millions of years, so that we are now discerning the age of distincct phases in planetary formation
I am not clear why you would view a systematic improvement in technology that reduces the errors of the estimates to be a "constant insult". Rather it seems a tribute to human ingenuity and perseverance; something to be celebrated, not denigrated. It seems that your motivation is frustration that the evidence based estimates do not align with your beliefs. That does not justify your baseless and ill informed attack. By all means declare that your faith forbids you to accept the evidence, but please do not misrepresent that evidence, as you have done here.
