The history of Earth as the length of a human’s outstretched arm - representing 4.5 billion years of time.

At this scale, humans emerged so recently that we could be filed off from a microscopic slice at the very tip of a fingernail.

DEEP TIME: If the timeline of Earth were mapped onto the human arm, it would begin around the shoulder where the earth formed about 4.5 billion years ago. Animals originated within the palm, but the myriad forms alive today exploded onto the scene around the first knuckle, in the Cambrian period. Blocks along the fingers represent the periods that followed, such as the Jurassic (dinosaurs) and the Cenozoic. Humans evolved at a microscopic slice at the tip of a fingernail.

And in about 200 million years, any trace of humanity will be nearly impossible to find…

that's why we don't have alien visitors. It's just freaking hard to catch the right moment when there's someone to talk to.
