Our heroes are human heroes. That's a very new situation. Most other societies have had, right at their center, the worship of something transcendent: a god, a spirit, a natural force, the universe, whatever it is -- something else that is being worshiped. We've slightly lost the habit of doing that, which is, I think, why we're particularly drawn to nature.
The other thing about modern society and why it causes this anxiety, is that we have nothing at its center that is non-human. We are the first society to be living in a world where we don't worship anything other than ourselves. We think very highly of ourselves, and so we should; we've put people on the Moon, done all sorts of extraordinary things. And so we tend to worship ourselves.
