Main article: Logarithmic timeline

This timeline shows the whole history of the universe, the Earth, and humanity in one table. Each row is defined in years ago, that is, years before the present date, with the earliest times at the top of the chart. In each table cell on the right, references to events or notable people are given, more or less in chronological order within the cell.

Each row corresponds to a change in log (time before present) of about 0.1 (using log base 10), similar to Renard numbers.
