Take for example the migratory patterns of birds. They fly thousands of miles and navigate by the stars to go to and from their habitats. Fish and various other animals have patterns of communication and habits that reflect the awesomeness of their creator. The human body alone, is a marvelous complex machine that can even heal itself. Add to this all that we know about Science and Math and Biology and the natural laws.
Creation shouts loudly of a creator, who pays attention to detail.
From the atom and subatomic particles to the largest animals of the earth, a master designer is easier to fathom than a mere accident. Look at the details. What we know about the cells of our bodies has given us much hope for medical breakthroughs every day. That which we have learned about plant life and their cell structure also tells us of a master designer. The word of God also tells us that this Creator was an exacting God of great detail.
