It's fun to really think about these scales. Earth has been around quite a while since big bang. Actually a one-third is pretty amazing number when you start to think about that. That is age of Earth is about third of age of Universe... And then Universe will be around for a very very long time after the planet is unrecognisable.

On other hand Earth is just tiny thing in solar system, which is tiny thing in galaxy which is small thing around general area which is tiny thing in great scale of things...
