One of the more frustrating aspects of your question is that you are too ignorant of the history of science to now already know this.
Yes, because it indicates your very limited knowledge of the issues again. Despite that limited information you have chosen to make claims based on it. Now, I am going to ask you again, do you have some substantive information on radiometric dating?
The POINT was that you would know this answer if you had any knowledge of the field.
Now, if you are in a thread entitled the age of the Earth and you want to discuss it and you are wondering how we come to the age of the Earth, what are you doing then?
This ignores that there is a lack of evidence that the Earth was molten several times. A lot of things could be, however, this doesn't address the evidence for what is. Meteories also happen to fit the evidence of the age of the solar system that is entirely consistent with the age of the Earth from rock formations.
