Radiometric dating age of earth
Many great thinkers throughout history have tried to figure out Earth’s age.
In the early part of the 20th century, scientists still weren’t sure how old Earth is.
Nowadays, scientists use radiometric dating of various sorts of rock – both earthly and extraterrestrial – to pinpoint Earth’s age.
These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.
As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.
