Radioactive studies and lava flows offer evidence that there has been abundant water throughout Earth's geologic history.
Life has been present on Earth for approximately 85-90% of its 4.6 billion-year history, with evidence of microbial life dating back around 3.5 billion years. This indicates that microbial life existed on Earth for most of its existence.
Geologists have divided Earth's history into manageable units called eons, eras, periods, and epochs. These divisions help scientists study and understand the Earth's geological and biological history over millions of years.
The geologic time scale helps to organize Earth's history into manageable segments based on significant events and changes. It allows scientists to study and understand the timing of key geological and biological events, such as mass extinctions or the formation of mountain ranges. By providing a framework for organizing this vast expanse of time, the geologic time scale aids in our understanding of Earth's evolution and the processes that have shaped our planet over billions of years.
because the time span of earth past is so great geologic
The table you are referring to is likely the Geologic Time Scale. It divides Earth's history into different time periods based on significant events and changes in the planet's geology, climate, and life forms. These time periods are typically grouped into eons, eras, periods, epochs, and ages.

First organisms formed, pangaea came together, homo sapiens lived. There are lots of good images on google.
Their evidence comes from rocks at earths surface.
