I disagree about it being evidence of design although it certainly doesn't disprove design. It seems completely neutral to me, not supporting either side (design or lack of design). The only reason to attribute it to design I can see is that you want it to be. Btw, I'm not sure what your paragraph on Christ has to do with this topic.
I wasn't debating that there is order in the universe although I'm sure some people would like to debate that depending on how you define order. Either way I see no need to go into this since my real point was that your assumption of (a) was invalid.
If you wan't to provide other evidence that's fine but I do not believe you have shown order is evidence for design. What you are doing with your last statement is creating a God of gaps. We don't know how the universe began, so instead of just saying "We don't know" you say it was God. Btw, there are several theories for how the universe began (but that's not the point).
Emotional attachment can be very helpful for survival. For example, how long do you think humans would last if mothers didn't care about their children.
I would argue that those things are not good for our survival. Killing humans is obviously not good for the survival of humans (I don't think that needs to much explaining). Stealing and infidelity certainly negatively affect social cohesion. Having more stable societies is certainly a survival advantage and many many other species have their own rules for their societies (bees, ants, apes, wolves, etc.)
This is basically irreducable complexity which once again could be a whole other thread but in response to how one chromosome becomes two it would be through mutation. Remember evolution doesn't have a goal and then build something to get there. I'm surprised you said you were a biology major because you say evolution is "only a theory" but anyone who is well versed in science terminology knows that a theory in science is not the same as a hypothesis. Quite the opposite in fact. I doubt you would say the theory of gravity is "only a theory". The word theory is used because in science, unlike religion, NOTHING IS EVER PROVEN, only things that have never been disproven.
I would suspect waiting for the right mutation to occur would not be a good use of your time.
Yeah I probably indulged too much on the evolution topic myself. In the end of course you have to believe in whatever you believe. Belief is not a choice but that doesn't mean it can't change. I can't choose to believe in God because I simply don't see the evidence. No matter how hard I try, I can't make myself believe in something I don't see the evidence for.
