Neil Degrasse Tyson accuses science fiction writers of a lack of imagination. I don't think so. I think they might be too creative. Regardless of how they evolved, the most basic commodities don't offer that much variation. If you build a house, it makes sense to make it a box. You probably have eyes, so you want windows. You'd have an anus, so you'd want a facility to dispose of your waste. If you are carbon based, you would want running water. You don't want a sore ass, so you'd have a couch.

So my theory is that in every intelligent alien race someone at some point walked through a door, sat on a couch and looked out a window.
