Many Theists have a big problem with the idea of life on Earth starting out in the primordial soup and muck billions of years ago. They say it degrades life especially human life, to think that it came from pools of water and perhaps might have initiated with a spark of lightening. They instead, like to think we were created by God in his image, purposely made separate from all the other creatures.
Well besides the evidence that we did evolve from early microbial life in the primordial soup billions of years ago I say that our origins make no difference about what we are today. Even if we did evolve from simple life forms, other primates, that makes no difference to the value of a human life, and what we are capable of. We're still human beings, we still have a conscience, we're still capable of making moral and ethical actions, and are still faced with all the same problems we face today as if their were no deity: how do we create and sustain a just society?
Think about this on the human individual level. We all like to think that we were conceived in a loving marriage between a married man and woman. However many of us weren't. Some of us are the products of one night stands, others complete accidents. But whether we were conceived in a loving marriage or are the products of a rape, it makes no difference to the value of our lives. We're still a human beings, still capable of making moral decisions (unless your mentally handicapped), our lives have no less value as human beings regardless of how we are conceived. It's as if to say that a person born from a marriage is worth more and is better than a child born out of wedlock. That's absurd and would contradict Christian morale. So whether or not we came from the primordial soup or were handcrafted by a deity makes no difference in what we are today: we are human beings.
