Well, I think the idea is that there must be energy and matter to begin with. The energy animates the matter. It is then possible for animated matter to form structures that become self-replicating. It's not so much that matter deliberately forms self-replicating structures - there is no deliberate - it is that matter forms all sorts of structures and the self-replicating ones necessarily become more common. It just needs a long, long time to bake and as soon as one structure can replicate it spreads. But all the time there must be a source of energy. That would be the sun.
A car can't sustain itself because it is not designed to nor has it been selected from a pool of designs for its ability to self-sustain.
You may well ask where did the energy and matter come from in the first place and my scientific reply is: I have no idea.
I think people exhibited moral behaviours before they could read and write or speak. My theory is that our basic moral behaviours are genetically programmed and are managed by our emotional brain. So we feel either motivated or reluctant to do things. A mother normally feels protective to her baby. So the written down morals we use today are the codification of those innate emotional responses with some adjustments for group benefit that we figured out with our cognitive brains.
It is very complicated because our instinctive responses, which exist to protect us from perceived danger, aren't all optimum for modern society living. So we have to moderate ourselves by trying to abide by codes that we interpret rationally. But our emotions are much stronger than our rationalizations so it helps us a lot if we can anchor the counter-instinctive codes to a "safe" emotional concept.
I'm not sure I have described that clearly. I don't fully understand it.
Trivial example. Bungee jump. I've done this! Standing on the edge of that bridge in New Zealand ready to jump. Legs tied to a perfectly safe cord, the length adjusted for my body weight, the rig used many many times everyday of the week without anyone being injured. Rational brain perfectly happy. Emotional brain was convinced I would die! I was shaking, sweating, feeling sick and dizzy. My legs felt heavy as lead. It took me many deep breaths and a sustained conscious struggle to placate my instinctive emotional response enough for my emotional brain to allow my motor controls to move my legs. It was the most intense and invigorating sensation. Thrilling, perplexing and terrifying. After I eventually managed to leap it was one of the most thrilling and satisfying things I have done. I was just laughing uncontrollably as I recoiled a few feet above the river's surface. What a total rush. I recommend it to anyone!
I've only done a bungee jump once. I suppose if I tried it again I would still be terrified. The more you repeat it and survive, the less your instincts hold you back. Instincts learn very slowly and you cannot just tell them what's what. You have to show them, it seems.
