Sorry but you have NEVER addressed the uniqueness of humans. Why are we compassionate? Altruistic? Why do we love something when their is no logical reason? Why do we create and appreciate beautiful music? Why do we create beautiful art? Dance? There are so many things that cannot be explained away by laws of gravity and such.
It should be mentioned that a number of these behaviors have been identified in other species – dolphins, for instance, display altruism even when it doesn’t aid their own survival (and, in fact, may put that survival in danger).
For instance, last month, a couple New Zealanders were swimming in the ocean when they were attacked by sharks. To their surprise, a passing pod of dolphins surrounded them, and proceeded to protect them for the next 40 minutes until the humans were out of danger.

This sort of behavior is well-recorded in dolphins. That stuff about dolphins saving drowning people and bringing them back to shore isn’t a myth – they really do that. If you’re drowning in the ocean and a dolphin is nearby enough to notice, it will usually go out of its way to get you back to land.
What instinctual basis could there be for this? They derive no benefit from helping humans. Heck, they couldn’t even have learned this instinctually through dealing with other dolphins – other dolphins don’t tend to drown, and even if one were drowning, you could hardly give it a ride back to the shore to solve the problem.
Other activities classically viewed as “humans only” have been observed in the animal kingdom, too, often in remarkably surprising places. Octopi in the Mediterranean have been observed decorating their nests with white walls and red rooftops – just like the beachfront homes on the shore near them.
Chimpanzees, our closest relative in the animal kingdom, have even been recorded displaying what looks an awful lot like culture-influenced behavior rather than instinctual – travelling out of their way to dance around in front of a particularly spectacular waterfall, for example. (And not just once, but as a regular occurence.)
