[Mr. Nobody]

It is intelligence that developed out of our ability to recognize patterns, when competition forced us to kill prey more efficiently that we discovered death and mortality. Homo Sapien watched animals die, blood on his hands and felt guilt, shame, he developed the concept of heaven, the circle of life and afterlife, resurrection, re-birth, the concept of forgiveness, fairness, good, evil and finally the concept of religion in the quest for reason. Society advanced and society took on life as the highest form of organized matter, complete with self preservation of this society and sacrifice of the individual in wars and conquest, akin to all other animal societies, most notable the insect ant colonies.
The questions of the meaning of life does not have a reality, it cannot be asked independently, because it was derived from Homo Sapiens as a tool to gain orientation within a cruel world where life depends on death.
