Venus, I don't understand what any of this has to do with anything? This thread is about evolution and you've hardly even talked about evolution. You've just quoted biologists talking mostly about other things.
This thread isn't about how atheists feel, to which there is no answer as they are all individuals and are arguably the most varied bunch on the planet. I've literally met fellow atheists with whom the only thing I agree on is the non-existence of god.
Moreover, the complexity of DNA isn't due to evolution, it was already complex before evolution got started, and altruism is so far off from the OP I don't even know how you got there.
