Well, I didn't dig too deeply into the old thread, but if you're asking why we are so lucky, I guess I don't understand the question. The universe is simply too vast to know that we ARE totally unique. It seems rather arrogant to me to assume that, given that virtually incomprehensible vastness, that we are the only planet with life, whether one believes we are created by a higher power or not.
Incidentally, you appear to making an assumption that I am an atheist. That's understandable given the polarized nature of culture today. If somebody weighs in or makes an observation, it is natural these days for people to draw their lines and place that person on one side or the other, and the only two options, I'm guessing, would be Christian and atheist. My beliefs are irrelevant. Either we are seeing stars that are billions of light years away or we are not, and all considerations of spiritual beliefs are entirely out of the equation of whether or not that is true.
Evolutionary science, like ALL science, makes assumptions. You can't get by in life without assumptions. I walk out to my car every morning making an assumption that it is going to start. If we didn't make assumptions we would simply stagnate to inertia. My problem with fundamental religious belief is that it doesn't make assumptions, it makes extraordinary assertions. These assertions are sometimes, some would say often, contradicted by natural law. I can't help that. I accept the natural laws of my Creator on their own terms. To me it seems insulting to those laws to accept somebody's word for it that a human being resurrected from the dead when natural law would tell us that this is impossible. The burden of proof of such a thing rests with the person making the claim, and not with me or anybody else to disprove. This does not mean that I don't believe in a Creator, nor does it diminish my capacity to do so.
