Estimates by uniformitarian geologists of the age of the Earth and the beginning of life give about 4.55 billion years and 3.5 billion years ago respectively. These estimates are primarily based on radioactive dating of meteorites and fossil specimens. Most scientists today conclude that the Earth formed by natural processes, specifically by the accumulation of debris orbiting the sun billions of years in the past.<ref name=nebula>"[http://science.jrank.org/pages/6265/Solar-System-solar-nebula-hypothesis.html The Solar Nebula Hypothesis]."
