Where are they?

[Mister Obvious]

Life on the other planets in our own solar system (or at least "intelligent life" which could communicate with us) can only live on the area of the planet it comes from. Why would it come here?

Hell, we can't even live on all areas of our own damn planet, yet we're expected to go colonize other planets, or for aliens from other planets to be able to come here?

Pft. It's never gonna happen, or at least if it does, it won't be sustainable on any level.

Accept it.
