Age of Earth

Early geologists might have suspected that the Earth was older than 6000 years because of the natural architecture on the Earth. Places like the Grand Canyon and Bryce Canyon have such detailed and crafted layering and shaping that could not have been as young as 6000. The layers of strata develop by a certain number of years, the number of layers reflecting how old that area of the Earth may be. It's as if we could dig and dig and dig until we reached the first stages of Earth. Each pile of dirt we bring up represents however many years ago. Every shovelful brings us one scoop closer to the beginnings of Earth because everything we're digging up is older and older, every time we're digging deeper. Geologists can look at the strata from places around the world like the Colorado Plateau and use it to measure how long ago the Earth was "born".
