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.
Earth is 4.6+ billion years old. It's seen a lot of birthday cake in those years, but it's really only seen eukaryotes for about the last 2 billion.
