I believe in the Ancient Sumerian gods, Marduk created the universe, as well as man. We do not all live for a soul-bound purpose, many humans already wander not knowing why they do it. Marduk created man so he could keep the primordial chaos away from Earth, but now there are billions of us and many are left to their own leisure. Me, personally, I believe that the meaning of life is to find meaning in life. Man is free, no matter how many excuses he comes up with, he is free, so be free.
