The earth has been around for approximately 4.5 billion years. Wrapping your head around that is quite a struggle, especially when you're trying to compare it to how long humans have been around, or when animals first took steps on land. YouTube channel Skunk Bear took the time to show, using a football field, a timeline of earth, from when it first began to present day. And when it's laid out like that, it certainly shows how much happened before we were around and how insignificant we are in the grand scheme of things. Definitely worth a watch.
