Suppose The Great Barrier Reef is the world's largest coral reef system, composed of over 2,900 individual reefs and 900 islands stretching over 2,300 kilometers. It is located off the coast of Queensland, Australia, and is home to a diverse range of marine life, including over 1,500 species of fish.
Can we infer that "The Great Barrier Reef is entirely man-made"? Yes, no, or maybe?
