Based upon radiometric dating the age of the earth is Sex ipad video
Plate tectonics then threw the crushed rock back into the interior of the Earth, removing the old evidence and turning it into new rock.
In the early 20th century, scientists refined the process of radiometric dating.
Scientists also must battle an issue called the Great Unconformity, which is where sedimentary layers of rock appear to be missing (at the Grand Canyon, for example, there's 1.2 billion years of rock that can't be found).
There are multiple explanations for this uncomformity; in early 2019, one study suggested that a global ice age caused glaciers to grind into the rock, causing it to disintegrate.

Some people have suggested the most hardcore flat-Earth believers did not give up their fight until they could hold a GPS receiver in their hand that gave their latitude-longitude position.
Will sceptics of old-Earth geology wait until mass spectrometers are in every home before finally conceding that the earth is more than 6,000 years old?
A 2009 poll found 39% agreed that “God created the universe, the earth, the sun, moon, stars, plants, animals and the first two people within the past 10,000 years”.
They've attempted to predict the age based on changing sea levels, the time it took for Earth or the sun to cool to present temperatures, and the salinity of the ocean.
