Age of the Earth

The Earth is 4.54 billion years old. This age was determined by radio-active analyzing uranium-rich samples of rocky material across the globe, including meteorites. Independent analysis of the Sun's mass and luminosity suggests that the solar system is roughly the same age as the Earth, as are most meteorites. While the Earth's old age is not evidence of evolution per se, it does show the plausibility significant genetic divergence over such timeframes.
