I have a son, and he's awesome and I can't imagine life without him, nor would I want to experience life without him, but I find the propagation of our species the least interesting purpose of life. If nothing is done during that life except propagate, then nothing is happening of interest, just people hedonistically living. What is done with your life is the most important purpose, otherwise we are just cycling around to no end.
