The Cosmic Calendar is a way of visualizing the history of the universe on a scale of one year. In this analogy, the Big Bang occurs at the beginning of January 1st, and the present day is at the end of December 31st.

The last 14 seconds of the Cosmic Calendar represent the entire history of human civilization.

Here's a breakdown:

* The first 9 months: The formation of the universe, stars, galaxies, and the solar system.

* The last 3 months: The formation of Earth and the emergence of life.

* The last few days: The evolution of complex life, including dinosaurs.

* The last few hours: The rise of mammals and the appearance of humans.

* The last 14 seconds: The entirety of human civilization, from the first civilizations to the present day.

This illustrates how relatively recent humans are in the grand scheme of the universe's history. It emphasizes the vastness of time and the rapid pace of human progress in comparison.
