I am going to try this a different way.
DOC, what do you think the difference is between the three following scenarios:
1) Every living thing evolved from one single blue-green algae whateverunittheycomein*.
2) Every living thing evolved from one or more blue-green algae whateverunittheycomein*.
3) Every person that has ever lived evolved from one single ape*.
4) Every animal that ever lived evolved from one single reptile*.
What is the difference and why do you think it would matter?
You see, to me as an atheist with a little bit of a Buddhist background (via my mother), every living thing has beauty and value. I would feel no less of myself or my origins if I learned that I am ape, a bacterium, or an angel. One of the loveliest parts about not believing what churches tell people, is that you no longer have to follow a hierarchical system that places values on things based on what seems to be an arbitrary scale. Of course, I do feel greater kinship with people, then other apes, then so forth across the tree of life, but kinship does not have to equate to worth.
In other words, don't feel bad that you are just another hominid, there is nothing wrong with it.
* Note to the peanut gallery, I am not suggesting any of these statements are true, just trying to frame them in DOCspeak.
