When people think that science is inferior to the "human" realm of art, feelings, and communication, this hides an unexamined assumption that humans are superior to other creatures, including extraterrestrials.

If humans are really so much more nuanced than the natural world, then aliens have little hope of surpassing us. If, however, the natural world is just as nuanced as humans, or much more so, then we have no trouble recognizing the importance of all life on earth and beyond.
