EARTH

IS EARTH A GOOD NAME?

Now we all know why the Earth is called Earth, right? because of the ground basically, dirt, soil, Earth. I'm not so sure that it's the best name for our planet though, for example, if an extraterrestrial being discovered our planet and had to name it simply by looking at it well, they would probably call it 'Ocean' or 'Water' thats presuming they can speak English of coarse.
