A principle basis for Old Earth theory is [[radiometric dating]].  This rests on the assumption that [[radioactive decay]] rates have always been constant, which is disputed by Creation scientists.

The discipline of [[uniformitarianism]] is also a basis for assuming an old Earth. Extrapolating the rate of geologic processes backwards in time yields an Earth substantially older than the Biblical 6,000 years. Uniformitarianism is also based on assumptions, however; namely, that many geologic processes were acting at the same or similar rates for the whole history of the Earth.

Other theories held by Old Earth proponents include punctuated equilibrium, which suggests gradual change over time with periods of rapid change.
