How old is the earth based on radiometric age dating
Since we did not observe the initial conditions when the hourglass time started, we must make assumptions.All three of these assumptions can affect our time calculations.Once the rock cools it is assumed that no more atoms can escape and any daughter element found in a rock will be the result of radioactive decay.The dating process then requires measuring how much daughter element is in a rock sample and knowing the decay rate (i.e., how long it takes the parent element to decay into the daughter element—uranium into lead or potassium into argon). Half-life is defined as the length of time it takes half of the remaining atoms of a radioactive parent element to decay.Types of igneous rocks include granite and basalt (lava).
There are certain kinds of atoms in nature that are unstable and spontaneously change (decay) into other kinds of atoms.
For example, uranium will radioactively decay through a series of steps until it becomes the stable element lead. The original element is referred to as the parent element (in these cases uranium and potassium), and the end result is called the daughter element (lead and argon).
The straightforward reading of Scripture reveals that the days of creation () were literal days and that the earth is just thousands of years old and not billions.
Proponents of evolution publicize radioisotope dating as a reliable and consistent method for obtaining absolute ages of rocks and the age of the earth.
This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).

Scientists use observational science to measure the amount of a daughter element within a rock sample and to determine the present observable decay rate of the parent element.
