Everyone comes from Earth. No, not that one. Not yours. Well, you come from your Earth.

I suppose I should clarify. One of the most startling thing scientists find upon making first contact with the Federation is that nearly every species named their planet Earth. In their own language, of course. They named it for what supported them, helped them grow, and allowed them to flourish. Moons, stars, interstellar objects, those all have wildly different naming schemes.

But, everyone comes from Earth. Or, the closest thing they have. Most aquatic species in the federation actually come from Sea, for example. The avian species largely come from Sky.

Now, this isn't always the case. There have been a few one-off races with unusual worlds, but they're pretty self explanatory in context. The Aruill come from Island, because their world is comprised of large archipelagoes rather than substantial landmasses. The Cutroolim come from Valley, because their uniquely damaged world has a small habitable zone formed as a massive rift valley. The Variff come from Twilight, because their world was tidally locked and only the twilight between day and night could support life.

But still, the meaning is the same. Everyone comes from Earth. Everyone, from Sky to Sea to somewhere in between, comes from a world that supported them, cared for them, and is named for what it is. Everyone comes from a world named for their home.

In fact, it's such a common aspect of interspecies exchange that "Everyone comes from Earth" is rapidly becoming a near universal colloquialism. It roughly translates to something along the lines of "No matter the differences between us, there is common ground." That doesn't quite get the intent of the phrase, I know. But, I'm sure your kind will pick up the nuances of the phrase as time goes on.

So, human. Thank you for joining the Federation. We welcome yet another Earth, and look forward to what you bring with you.
