While the fossil record is incomplete, it still helps lend evidence to the Theory of Evolution.
Fossils are relatively rare because of all of the elements that have to fall into place before an organism can become a fossil.
We’ll start with the most familiar, carbon dating, and later talk about other dating methods. In general, radioactive carbon 14 (C14) is created when nitrogen, high in the Earth’s atmosphere is struck by high energy particles from space.
The Bible has records that show about a 6,000-year history back to the beginning.
But for the evolutionist, billions of years is the assumption.
The technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating.
Many isotopes have been studied, probing a wide range of time scales.
