What were the 3 methods used in determining the age of the Earth?
The three main methods used by Evolutionists were the uranium/thorium-lead method, the rubidium-strontium method, and the potassium-argon method. These all require a constant decay rate over billions of years, an isolated system (over billions of years), and known initial conditions. None of these assumptions are provable by finite human beings. Even some Evolutionists, such as Frederick Jueneman, are beginning to recognize the problems.
