Sometimes I'll be in an office building, or on a job site, or in a hospital room, or even just taking a big shit.

And I'll look around and think to myself "Everything here is man made. It all comes from people." And then I'll just kinda marvel at the productive and transformative nature of human beings.

In deep space, that only gets more true. The water you drink, the air you breath, the lights you see by - all the product of human enginuity.
