I take it from your post you don't attach any importance to the human race. As I see it you think we are just another creature who happen to inhabit this planet.
LOL just because I know that we evolved doesn't mean I attach less importance to the human race than you do. I could argue that I attach more importance than you do, since I believe Love is the most important thing in the world and I believe it is an innate characteristic of humans (and to some extent other creatures), not something injected into us by an external God, but something that naturally arises between us. As far as you're concerned humankind is only important because God made it important. As far as I'm concerned humankind is important of its own sake. But we don't need to argue who thinks humankind is more important do we? It's peripheral to the discussion at hand. You made a statement that yours is a reasonable stance, and I think your next sentence shows that it is not....
I look at it in a completely different way. I don't buy into the theory that man evolved from another creature like the ape or the monkey. Personally I think man was a completely different species brought into being by God. Yes, evolution has taken place but all within the confines of that unique species.
Which [hu]man? Homo Sapeins, Homo neanderthalis, homo erectus, homo australopithecus or any of the other species that romed this earth in the last million or so years? There's a mountain of evidence to show that humankind wasn't a single species creation of God's! you may not 'buy into' it, but that shows your argument to be unreasonable.
Chimpanzees obviously make decisions.
