Suppose The Great Barrier Reef is the world's largest coral reef system, located off the coast of Queensland, Australia. It is composed of over 2,900 individual reefs and 900 islands, stretching over 2,300 kilometers. The reef is home to a wide variety of marine life, including hundreds of species of fish, coral, and other organisms.
Can we infer that "The Great Barrier Reef is entirely man-made"? Yes, no, or maybe?
