The validity of radiometric dating is subject to the assumptions upon which it was developed.

The whole pracess started with an assumed age and expanded out from that position. No attempt was ever made to challenge that assumption.

It's to the benefit of evolutionists to go for the really old earth model. It's the only thing that will allow for enough time for their theory so that they can (try to) convince others that it's valid.

The ToE demands a very old earth. Take away the old earth and their theory has nothing to stand on.

The only assumption required for radiometric dating using techniques that rely on measuring ratios of daughter elements is a constant decay rate. Not all radioisotopes decay in this manner, but uranium does.

It is reasonable to believe that a given sample of uranium bearing rock could possibly have formed with exactly the required proportions of daughter elements present to falsely present an appearance of being billions of years old. It is insanity to believe they all did.
