Godless Evolution in a Nutshell

beliefnet
As the universe evolved heavy elements were created in hot massive stars that exploded seeding the universe with heavier elements that could react as elements do because of energy considerations to form compounds.   Some of the lighter elements, carbon, oxygen, and nitrogen, commonly reacted with hydrogen to form methane, ammonia and carboxylic acid, which in turn reacted to form amino acids the building blocks of life.  As stars and planets formed out of dust clouds in space those amino acids were distilled onto planets that were suitable in distance and energy flux to contain liquid water. Eventually life formed on such planets.  Hardly something from nothing.  But no creator necessary, simply physics, chemistry and energy.
 
As life evolved it became necessary for survival to sense and react to the environment in which life existed, as finding nutrients and avoiding being one, was necessary for survival and reproduction.  Those organisms that were good at sensing and reacting to the environment reproduced and thrived until something that sensed and reacted better came along and became locally dominant.  Repeat, repeat, repeat, until part of the package needed for survival was in addition to experiencing and doing, thinking, planning, and feeling were added to the mix.  In particular feeling good about the opposite sex to form pair bonds to facilitate getting infants to be reproducing adults.  Thinking and planning are added relatively early in evolution as all mammals and birds appear to do so.  

Those animals that have evolved to assist humans in guarding, herding, rodent control and other needed functions around settlements have learned to sense human feelings of happiness, joy, wonder, and do things that create them in order to survive in the presence of humans.  See Facebook threads of cute animals doing things to please humans.
