(1) Is Value of who we are objective or subjective.
Each species evolves with instincts to ensure reproduction. With insects, spiders, many fish and molluscs, and some animals, not least rodents, sheer volume may be the technique. With others, including us, instincts promoting individual survival are foremost ─ and we're one of a few special cases because our infants are wholly dependent till about age five. So we've evolved a strong set of individual survival instincts, including a large kit of self-preservation instincts ─ which are exploited in many kinds of movies, and with daredevil live stunts (sadly for Alex Harvill, and he's not the first). We're also gregarious, so our place in the tribal peck order matters, and self-assertion may be rewarded.
In other words, we're valuable because we've evolved to think so.
