Getting a little tired of this Earth? Think you might want to get a shiny new one? Maybe one with less plastic bits floating in the ocean, more fresh air, and less annoying neighbors? If you have the right elements and enough free time on your hands, here's how you get one just like this one. This is a timeline of the biggest, most important periods in Earth's long history. To get a true sense of the scale of geologic time, note that the mammals that humans developed from didn't even show up till near the very end.NOTE: I found a lot of these images online through various museum sites, and I did not create them. If you see your artwork, let me know and I will either put your credit on it or take it down at your request.
