Did you get my answer on free will vs. omniscience?
I've asked this of other atheists, and they couldn't give me an answer....
My understanding of atheism is that we (humans) are just a cosmic fluke - a series of mutations and chance actions with no meaning or driving force (call it lack of an "intelligent designer"). Basically, all of what we see around us fits this concept. Assuming that I'm right in my understanding, what makes the life of a human more valuable to you than that of the cattle in the field? Not you, or your family, or anything like that; but, the life of some kid in Kansas who gets shot by someone else. Why is that murder "wrong" (which, I see no basis of what "right" and "wrong" would be to an atheist, either)?
