A Fortuitous Set of Coincidences?

Can we look at the universe and decide that the proper mix of hydrogen, oxygen, nitrogen, carbon dioxide, the proper distance of the sun and its production of light and heat and how it reaches earth and the atmospheric conditions that filter out the harmful ultraviolet rays but allow in the life-giving photosynthetic pleasures of the plants, that the way water behaves in its unorthodox way (compared all other liquids) where it ceases to contract and inexplicably begins instea...d to expand as it does when the temperature descends below forty degrees, that acorns the size of thumbnails grow into oak trees, that these same trees exhale oxygen while we inhale it and also complement each other in the case of carbon dioxide, that the various systems that cause biological being are in place in humans, squirrels, cats, birds, centipedes and cause us to reproduce, live; how is it that grass revives each spring? how is it that babies are born from the gift of man and woman, of male and female in all the species of living things? how is it that even the most rudimentary rock exists? What in the world, may I ask, gives the rock its rockness and its weight?
