I think we like the idea of these advanced alien cilivisatons because it gives us hope that we too one day may develop the technology to leave our Solar system, perhaps even the galaxy. 

But odds are that will never happen. We're stuck here, for good and bad. This is where human life evolved, and this is the environment we need to survive. 

Instead, there’s a being on planet Remulac posting on their iPad-equivalent about why those aliens from Earth keep not showing up. 

If anything, we have learned that our model of constant growth and increased consumption doesn’t work, that it’s most likely impossible to become a space-fairing species whilst utilizing that model, and I expect other life forms to have adapted a more balanced approach. If we ever manage to do that, we just might be surprised to learn that alien life has been out there the whole time, waiting for us to figure it out.

Anyway, does anyone have thoughts on what might be the rarest, most valuable resources on our planet? I’m pretty sure the true answer isn’t what you might expect.
