Layers in glaciers show a history much longer than 10,000 years, and radiometric dating places the formation of the Earth at 4.5 billion years. Light from galaxies is reaching us billions of years after it left, and the expansion rate of the universe dates its age to 13.7 billion years.

Based on relative and absolute age dating techniques, geologists now think that the earth was formed about 4,600,000,000 years ago.
