The American astronomer Carl Segan (1934-1996) first suggested a "cosmic calendar" as a way of helping people understand the history of the Universe.
He put everything in the scale of a single calendar year: the galaxies are formed over nine months and Earth appears in September.
All human history is crowded into the last five minutes of the last day of the year. recent time has to be divided into seconds and fractions of a second. So everything that happened over the last 475 years takes place in less than the last second of the last minute of the year.
