If you found a masterpiece would you exclaim, "it made itself? If you found a house fully stocked with food, with all the things you need to survive and with even things that you enjoy, would you say "No one made this house? You know the answer! Yet you yourself are a masterpiece of creation, you have a marvelous brain that surpasses even the most advanced computer in it's ability to reason, and create beauty. The earth is the house that we live in and it is fully stocked with enough food for all and supplies us with even more, with things we enjoy. If left alone it can even cleanse itself of all pollution if the sources of pollution are controlled. Romans 1:20 says "His invisible qualities are clearly seen from the world's creation onward, because they are perceived  by the things made." When we see a camera, a radio, or a computer, we readily acknowledge that it must have been produced by an intelligent designer. Would it be reasonable, then, to say that far more complex things-the eye, the ear, and the human brain-did not originate with an intelligent Designer?
