The Short Version
Humans have artificially created gold through nuclear transmutation, making this categorical claim false. Experiments at facilities like CERN's Large Hadron Collider have produced measurable quantities of gold atoms by bombarding lead nuclei, and earlier experiments converted mercury into gold. While these processes yield only microscopic, economically impractical amounts, the claim states gold "cannot" be created—an absolute that is directly contradicted by decades of verified experimental results.
