Planetary chauvinism

Planetary chauvinism is the belief that human society will always be planet-based (even if extended beyond Earth), and overlooks or ignores the potential benefits of space-based living.

[3] The counter-argument is that all the benefits of a planet can be achieved in space, e.g., by an O'Neill cylinder-type structure.

This is the assumption that intelligent life will always evolve in star systems similar to our own, that is, in stars of spectral class G.[5] Carl Sagan criticised this belief on the grounds that intelligent life has a greater chance of evolving on the most long lived stars.

[2] There are several hypotheses of the possibility of life originating in the universe in places other than planets.

[9] Similarly, the focus on surface-bound and territorial space advocacy, particularly for space colonization, has been termed surfacism, neglecting interest for atmospheres and potential atmospheric human habitation, such as colonization above the surface of Venus.
