These techniques utilize the physical parameters of the earth, such as ice cores, annual lake sediments, and astronomical cycles.

Nevertheless, there is substantial evidence that the Earth and the other bodies of the Solar System are 4.5-4.6 billion years old, and that the Milky Way Galaxy and the Universe are older still.

The principal evidence for the antiquity of Earth and its cosmic surroundings is: Spontaneous breakdown or decay of atomic nuclei, termed radioactive decay, is the basis for all radiometric dating methods.

In addition to the ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.

Most people accept the current old-earth (OE) age estimate of around 4.6 billion years.

Some half-lives are listed below: It follows that uranium-lead, potassium-argon (K-Ar), and Rubidium-Strontium (Rb-Sr) decay can be used for very long time periods, whilst radiocarbon dating can only be used up to about 70,000 years. This uses a simple exponential decay formula linking the original number, Po, of parent atoms in rocks and minerals to the P atoms now present, thereby enabling an estimate of geological age.

Mathematically, P = Po exp(-lambda T), where lambda = the decay constant and T = the period of decay. a zero initial number of D atoms, where P(or D) = the current number of P(or D) atoms, it follows that the age of a rock or mineral is computed as T=(1/lambda)ln(1 D/P).

A young earth is considered to be typically just 6,000 years old since this fits the creation account and some dating deductions from Genesis.

The crucial point here is: if YE theory can be established scientifically, then macroevolutionary theory falls!

Its crust is continually being created, modified, and destroyed.

As a result, rocks that record its earliest history have not been found and probably no longer exist.

This is based upon the spontaneous breakdown or decay of atomic nuclei.
