Do you think it is plausible that there would be advanced alien species with mindsets that we could at least understand the broad strokes of, given convergent evolution?
This is actually a cool question that has nothing to do with what's wrong with a TV show. I like it.
Let's assume we're talking aliens that use tools, have technology (space ships?) and not alien wild life. We barely understand cats, why would we assume we could understand 3 legged galumphs of the mountain acid marshes of Xenos Prime?
So I'm envisioning an alien society (more than one alien), that built a ship, and is travelling in space, and our ship, the Enterprise encounters them.
Aside from the problem that I can't envision an alien mindset different from my own, what is the probability that an alien species could achieve all that AND not have some mindset traits in common with humans?
Humans need food, so do aliens
Humans try to reproduce, so do aliens
Humans use tools, so do aliens
Humans develop interstellar space ships, so do aliens
I have no doubt there will be cultural differences, we have that here on earth (Japanese or chinese music is based on a 5 note scale, as opposed to the 8 note octave that everybody else uses). Clearly, some different ways of evolving in a subject for separate societies.
But I find it unlikely that the alien species would be incomprehensible to us. Psychologists, sociologists, and anthropologists would probably study them and identify how they view things and what real earth cultures they are similar to in their beliefs and behaviors.
