Lets for a moment agree that we a evolved and no God was involved in the matter.We were not created in Gods image and are not endowed with his qualities.
Do the emotions we feel mean anything or are they just an illusion without true meaning?For example is the more intense feeling of love toward your family just a leftover from evolution, where maybe at one time it served to keep you in a pack so you were safe from harm?Is a special attatchment to blood relations really benifical anymore?
Why do we have a need to be loved or to love or in fact do we?Are happiness a saddness just a chance fluke of nature that happen to fall in place to fit cetain happenings in our lives?Maybe some people feel happy at things that sadden us because of natural variation not evilness on their part?
Just why exactly and how did humans come to posess emotions?
