To be clear, I don't hold any strong position. All my previous comments are based on the assumption that the three premises I wrote in the very beginning of the first post are true, but I'm not arguing that those premises are true. I was just elaborating the implications if they were true:
1) To survive and to reproduce would be the closest thing to the ultimate purpose of life.
2) What traits we consider "good" or "bad" would actually be just what traits are beneficial for survival or not.
When at the end of the first post I brought up the fact that morality doesn't always align with beneficialness for survival, I was trying to do reductio ad absurdum.
Maybe the three premises were not all true after all. Maybe there's something beyond the physical universe*, from which some higher being impulsively created the universe out of boredom, in which case there would still be no ultimate purpose. Or the higher being created it intentionally and with some purpose.
This might also elucidate the common argument, originated by C. S. Lewis, that all human beings know something good or bad because God imbued humans that ability. A common misconception interpreting this argument is to say only theists can do something good. Knowing is not the same as doing. All humans have the ability to distinguish good from bad, regardless of what they believe in, or whether they want to do something good or not.
