Your survival time in Minnesota (where I grew up) in the winter time is not appreciably longer than in a vacuum, and you'd sometimes have to spend quite a long time to suit up in order to safely operate in such conditions. Most of the Earth is, in fact, covered in water (much of it cold), and most people would last maybe seconds longer than vacuum. The parent's point is right, IMHO. Humans may have first evolved in climates without necessity for clothing, housing, or fire, but we definitely need it in much of the world. And even places requiring these things still can thrive.
