Earth, Gaia, Terra Firma, the third stone from The Sun - averaging 92.917,931.7 miles from The Sun in any given year You've been here. We live here. The Earth's surface is approximately 70% ocean, and rising (due to Global Warming and the complimentary melting of polar icecaps). Approximately seven billion human beings populate the land formations known as continents, (and they are, for the most part, considered to be twits, as far as most of the rest of the intillegent universe is concerned).

Earth is the only planet in the Solar System known to possess coastlines - while some moons have oceans, and many planetary bodies "used to" have large theoretical bodies of surface liquid, our beautiful blue green world is the contemporary exception in this case, (leading many to believe that "life" is relatively rare in the universe). Earth is also the only planet in the Solar System, with ample clouds, where you can still see the surface from space, and vice versa. This condition may randomly be referred to as a Transitional Atmosphere - but, this situation being what most of us are currently used to, and referencing from, don't expect any of those references to be exceptionally relevant to anything anyone actually from here might be talking about.

Earth has but one moon, Luna (or The Moon), which always shows the same face to us - that is, we only ever see one side of the silly thing, and this is most likely due to an internal magnetic attraction (not, as some suggest with a straight face, a happy accident of rotational timing). What this means is, that: on the Moon, the Earth is always in the same part of the Lunar sky. So, if you were on the moon, and lost, you might be able to find your way by measuring the Earth's distance from the horizon. Remember this tidbit to tell your grandchildren, as no one in our collective generations has any remote hope of visiting any place more remote than Easter Island.

As with every other planet in the Solar System, the Earth is doomed. Eventually, an asteroid, or comet, or something similar, will smash headlong into us - and it will be of sufficient size and girth that dinosaurs everywhere will look up and say, "those poor bastards." Before that point, any beings wishing to remain in temporal physical form will elect to remove themselves to a secondary location.
