The length of time Earth has been around can be truly mind-boggling (let’s not even get into the universe’s scale of time). To help fathom the immense age of Earth and the comparatively meagre time span of human history, Business Insider has created this video.
It represents the timeline of Earth’s existence with a 3,942 kilometer (2,450 mile) coast-to-coast journey across America from Los Angeles to New York City. Along the trip we see the formation of our Moon, multicellular organisms evolving and the age of dinosaurs. Perhaps most interesting is that modern humans only evolved 175 meters (570 feet) from the finishing line of this journey.
