The doctrine that the Earth was of unlimited age allowed Uniformitarian geologists to evade [[explanation in science|explaining]] any [[phenomenon|phenomena]] by laws of [[physics]] and resort to [[Fog displacement|blurring]] them by ''“reckless drafts on the bank of time”'' instead.

Around the same time [[Lord Kelvin]] put his mind to deriving an age, and came up with a range between 20 million years and 400 million years.  He later refined that down to between 20 million and 40 million years.<ref name="ingv" />  More recent discoveries of radioactivity and mantle convection explain why the assumptions Helmholtz and Kelvin made resulted in dates that are much lower than current uniformitarian estimates.
