It seems absurd and inexplicable in many ways that evolution is responsible for our insanely complex minds and bodies to so rapidly and perfectly form inside the womb in only 9 months, we are then born and continue to grow for another 20 years, but soon thereafter start to deteriorate and die after only 75-90 years.
Not really in evolutionary terms the most important thing you can do is procreate. Once you have reached maturity and passed on your genes your purpose is fulfilled.
