While the oldest known rocks on Earth are about 3.5 billion years old, researchers have found zircon crystals that are 4.3 billion years old [source: USGS].
Based on the analysis of these samples, scientists estimate that the Earth itself is about 4.5 billion years old.
These must be accepted on faith in uniformitarian and naturalistic frameworks.
Recent research by a team of creation scientists known as the RATE (arth) group has demonstrated the unreliability of radiometric dating techniques.
The extreme temperatures of the magma would just destroy the bones.
So to determine the age of sedimentary rock layers, researchers first have to find neighboring layers of Earth that include igneous rock, such as volcanic ash.
Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.
Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem.
Starting with the Bible and developing a model for dating events in earth history will lead us to the truth.
The Bible gives us a much more reliable history of the earth as it was recorded by God.
Each of them typically exists in igneous rock, or rock made from cooled magma.
