To date rocks or other objects, scientists typically use radiometric dating.
Quick cooling or not having contact with the air can affect theoretical mechanisms for "resetting" the clock.
Some times radiometric dating produces impossible results.
Furthermore, the same method can produce different ages on different parts of the same rock.
Sometimes these are close but other times they are very different.
This is particularly important in light of the Biblical flood.
How a rock is formed is important to understanding its isotopic make-up and any dates derived.However, it is typically unknown and simply assumed whether these ratios of elements are the result of radioactive decay over time or other processes that have taken place in the rock.Ages of Rocks in Millions of Years Sometimes different methods used on the same rock produce different ages. She refuted hypotheses regarding the evolution of bipedalism and brain size. Scientists did not know that humans and apes were related before finding her. Why do scientists think that bipedal posture evolved in humans? So if these are real dates then you can hold a rock in your hand that won't form for hundreds of thousands or even millions of years yet.
