The Rest Is Just Gravy

Do you think animals contemplate if they have a purpose in life? Do you think they wander around, wondering if they are really fulfilling their purpose? My guess is probably not, yet the incredible planet keeps on spinning around just fine. So why do we seek out a purpose for our lives; I mean a purpose that is of a higher calling than that is expected of the animals that we share this planet with? It seems really absurd that we believe that we have some purpose other than to survive and reproduce. Beyond that, the rest is just gravy.
