Not that there'd be anything wrong with isochrons validating isochrons--the physics is well-established--but that ignorant claim is just not true:
Cyclostratigraphy confirms radiometric dating past 100 million years
And there's really no question that the sun can't be enormously older or younger than around four and a half billion years.
As for the flood, evaporite deposits could hardly result from a flood, nor is the enormous amount of bioturbation, including huge numbers of worm burrows, consistent with any flood. Not that creationists care about actual evidence.

I'll pick on your best Cyclostratigraphy
A popular argument for old earth is the Milankovitch cycle theory. The theory has necessitated the belief in multiple ice ages and of late has been incorporated toward everything from climate change to Isochon dating.
Famous astronomer Fred Hoyle once said: “If I were to assert that a glacial condition could be induced in a room liberally supplied during winter with charged night-storage heaters simply by taking an ice cube into the room, the proposition would be no more unlikely than the Milankovitch theory.”
First of all, the changes in summer sunshine postulated by the theory are too small to generate an ice age. Several other problems also render these cycles unlikely.
Ice-core samples reveal multiple, rapid oscillation (usually 100 year cycles) throughout the last Milankovitch period (100,000 years) those so called 100,000 year Milankavich cycles that they claim they see in the cores could just as easily represent 100 year oscillation cycles.

In order to revamp support for the theory, evolutionists garnered supporting evidence from deep-sea and ice cores. Sediment cores older 40,000 years old are very often dated using isochon methods. Isochon dating is in turn calibrated by these core sediments. Obviously this can be very circular in reasoning
Oh and contamination is also still a problem
