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.
There was no single estimate of the Earth's age in the mid 1800's and no good way to arrive at one. There were various attempts to estimate the Earth's age, working back from sedimentation rates and other geophysical phenomena. The attempts produced estimates from about 100 million years up to several billion years.
