Consider a salmon or an eel. They grow and when their biological clock tells them to, they just turn and. Nature is not a being or a force. Nature, as such, was created by God and is one of the mechanisms he created to control much of what he put into action. Consider now, if you will, that fish or other animals do not have what humans have - the power to reason.
Man can weigh things up and use reason to come to certain decisions or conclusions.
This force is not found in any other creature. Often some scientist will make some ridiculous statement about a certain animal or mammal having the capability to have an intelligence perhaps far greater than man. This is hogwash. God did not endow animals with intelligence greater than man. God made man to have dominion over all the earth and everything in it and on it.
