This is the third thread that I've addressed the first question and I'll respond the same way I already have.
There are problems with all of the dating techniques. I don't know how old the earth is.
How old is the lava dome at Mount St. Helens?
According to radioisotropic dating, the lava dome which formed from October 18, 1980 to October 26, 1986 is 0.35 to 2.8 million years old!
"Radioisotope dating is widely perceived to be the "gold standard" of dating methods and the "proof" for millions of years of earth history. But when the method is tested on rocks of known age it fails miserably."

The lava dome that formed on Mt. St. Helens formed in 1980, but the lava itself is much older. Think about it this way, you have a coke can that is shaken up, when it is opened, coke is often flies out. Was that coca cola fluid formed when it landed on the top or when it was made before the coke was even in the can?
And using such a nonbiased site like creationism.org doesn't help.
However, it is important to remember that all radiometric dating methods are based on three main assumptions:-
The physico-chemical system must have always been closed. Thus no parent, daughter or other decay products within the system can have been removed, and no parent, daughter or other decay products from outside the system can have been added.
The system must initially have contained none of its daughter elements or decay products, or at the very least we need to know the starting conditions/state of the decay system.
The decay rate, referred to as the half-life of the radioactive parent element, must have always been the same, that is, constant.
The highly speculative nature of all radiometric dating methods becomes apparent when one realizes that none of the above assumptions is either valid or provable. Put simply, none of these assumptions can have been observed to have always been true throughout the supposed millions of years the radioactive elements have presumed to have been decaying.
