1. "We" (not I) feel the need to believe in some higher power because of the crippling fear that death is final, and that there is some higher purpose. 2. The emotional need for other people is evolutionarily advantageous. There is safety in numbers, it takes 2 to make a child, etc. It's not a metaphysical need. It's chemical. 3. Not everyone does, so the question is meaningless. Morals are learned, so that "conflict" is just contrast. Again, nothing metaphysical there. 4. That's easy. The combination of 2 sets of DNA is what allows the population to be varied enough genetically to not get wiped out by diseases. Some will die, while others will live on. 5. Meaningless, non-specific question. Points to a lack of understanding about evolution. 6. I already answered the first part (or you aren't asking what you meant to). "Figure out"? Seriously? Do you think that there was some magical time that offspring reproduced so radically different from its parent that it couldn't be taught or observed? As if my parent was an amoeba, but now I have external genitalia? There are lots of questions that can't be answered by evolution, or science in general. But that's due to not currently having an answer. It's not chance. There may be odds that something will or won't happen, but it isn't like evolution tries to explain our existence as some cosmic roll of the dice. It doesn't take faith, not in the least. I'd like to address your last point. This is the bit that irritates me every time. You said "What we don't have answers to points to something so much bigger than evolution". It seems that you're implying religion. That's cognitive and emotional weakness at its worst. Not having an answer can not, and will never, point to something. Not knowing means just that. You (and I) don't know. It doesn't mean that it can't, or will never, be known.
