    Life exists due to several factors.  We have the right temperature, copious amounts of water an ozone layer to protect life from harmful radiation and an atmosphere.

    By sheer luck. Be grateful, with all the things that could have gone wrong in the last several billion years to prevent the formation of life on this planet, you live in one incredible envelope of luck. smile
