"For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. Professing to be wise, they became fools..." (Rom. 1:20-22)

The story is told of an experiment involving a young chimpanzee who always tried to slip out of his cage when the door was opened. Some atheistic scientists, who were working hard in trying to discover the origin of man, thought this young chimp was very intelligent, and was a good specimen to teach communication skills. For fourteen years, project directors labored diligently and patiently with this chimpanzee, providing things in its cage to enable it to form certain syllables. Finally, the day arrived when it seemed that the chimpanzee was actually going to construct a sentence from the symbols it had been learning. Word went out, and other scientists crowded into the room and gathered around the cage. At last, the first message from the world's most pampered, most cared for, most patiently trained chimpanzee was about to come forth. Millions of our tax dollars had been spent, and many, many years of patient labor had gone into this project. The scientists could hardly contain themselves as they pressed around the cage. They watched breathlessly as symbols were formed into words and into a sentence. The chimpanzee said, "I want out!" (From Paul Harvey)

After this, the chimp soon forgot what he had learned and was never able to form another sentence. Thus, the scientists after all their efforts only learned what had been clearly demonstrated in the first place and, similarly, God's creation forever substantiates His eternal power and Godhead.
