I was standing outside by my house and i saw a tree. Where does a tree come from? From a seed? and the seed comes from a tree? Which came first? What is the chance that the tree just happened to have roots, that happened to know how to obsorbed water, and the tree happened to have a trunk, which happened to know how to transfer water to the leaves, and it just happened to have leaves, that knew how to obsorbed light from the sun, and it just happened to know how to store it, and so on, and so on.
