What If You Fit Entire History of Earth in One Year

If you could fit the entire history of Earth into one year, humans would appear at 11:35 P.M. on December 31st.

Let's imagine the Earth's 4.54 billion year history is squished into one calendar year. If you crunch the numbers, you'll see that one second would equal 144 years.

Are you ready to begin our journey through time? 

Let's do it.

In January and February, you're better off staying inside. Constant harsh winds and rains can destroy even massive mountains in a second. At the end of February however, single-celled life is making its appearance near underwater thermal vents and in coastal waters.

In June, 60% of the Earth's surface is still underwater. Multi-celled organisms start popping up around July 17th but there's still crustaceous creatures living in the oceans of the world.

In October, you can witness the Continental Divide but there still aren't many plants.

Early November brings the first springs of plant life and starting on the 18th, there's an explosion of complex life. In just a few days, the oceans become crowded with fish. Creatures dub amphibians climb out of the water to spend some time on shore.

December starts out with flying insects that help spread plant life across the land. Dinosaurs show up on the 13th but their time on earth is short lived. An enormous asteroid smashes into the Yucatan and the force of the collision releases a heat pulse that spreads fire all around the planet. This fire roasts our giant reptilian friends. So the dinosaurs become extinct by the 26th of the same month.

However, the next day, Earth completely recovers spreading grass throughout the land on the 27th. This herbal food source gives rise to mammals and primates on the 28th and finally, the first humans start walking around on the 31st of December at 11:35 P.M.
