^ did you read the non-bold stuff?
Who says because the building blocks of nature are chemical processes like cells, amino acids and proteins, there is no beauty and value of nature. All that statement suggests is that we are a part of this world along with every other organism on the planet.
Yep, human consiciousness is a function of the human brain, not a gift from a deity. But it is this consciousness which allows us to experience our beautiful world and create wonders through art, stories and music.
The rules of conduct for societies have evolved throughout time. The events that structured the rules in 2000BC are not the same as today. In case you haven't noticed, not doing the following: murder, molestation, hate, anger, stealing and so on are not exclusively Christian morals. They are universal traits generally accepted by all human beings regardless of religious origin. The non-Christian cultures got their social rules from somewhere but it wasn't God. Empathy, caring, sharing, loving and other emotions are functions of the human brain which allow us to understand actions which are acceptable and which aren't. So where did they get them from since they worshipped a different deity? That's all that line is suggesting.
That's a mighty big assumption you make about not believing in an external deity as an easier path. Who says life is nothing more than the pursuit of our self-interests? Every person on this planet is concerned about their self-interests and has selfish traits, even you but is this is underlying reason for existing, hardly. You assume because people don't believe in a deity, they can't have emotions and view the world as a cold sterile existence. On the contrary, I view the world as a remarkable place filled with beauty and wonder. My place on this planet is to hopefully leave a positive mark on this world whether it be through my friendships, family or through other ways. Re-read the 7th point, and think about how challenging it is to try and live a life like that.
I think you misinterpret a rejection of religion as a rejection of humanity and morals. On the contrary, I feel it is embracing humans and morals on a different scale. I don't HAVE to follow doctrine and rules to be a better person, I just strive for it because it's the right thing to do.
