Because the story is short, it is only about one topic. There is not enough room to deal with more than one.
The story must begin quickly in a short story. This is not only to catch the reader's attention, but to keep the word count down to a short story level.
What exactly is meant by "human" terms? That everything is personified, or that the story is always told in the human perspective? If you mean human terms as in words or ideas that are human, I must say that it is because as far as the concept of story telling has been developed, it has been shown that only humans can appreciate a story and show that appreciation. That is to say, only humans can understand a story told to them, insofar as it is humans who have invented stories.
