Life is not warm and fuzzy (like Bradley said). Life is about survival and the continuation of DNA (that's why we like sex so much). We are the carriers, that's it, and because that's all there is many folks who claim humans are extra special "creations" don't care to face the bare animal facts about homo sapiens. By claiming that all of creation must have a creator, well of course that's true. However the universe, this planet, you and me are not examples of creation. We are terrific examples of opportunistic punctuated equiliria. Because we survive many organisms that count on us also survive. We see how a virus will evolve (quickly) when it finds a new habitat ex., human rather than ducks or chickens. Of course this evolution of virus also works for our benefit. A good example of this is syphilus. Less than a millenium ago syphilus would kill it's victims in a matter of months, yes mere months. By the 19th century VD patients were living for years with the active virus. What happened? The virus mutated in order to infect more people (no it wasn't getting a conscience or anything). A person who is too sick to get out of bed will not infect anyone or very few others. If the virus is not quickly lethal it's chances of survival to infect others is assured. Like I said this evolution took less than a thousand years.
So is a struggle for everything living. We should admire the fact that we actually have a larger hand in that than any god does. If we understand our position on this planet and live for now not for heavenly existencew we'll try harder (like the virus) to accomodate ourselves to our habitat not kill off the planet but help it live longer.
