Gold is a naturally occurring element that is found in the Earth's crust. Scientists believe that it is formed by supernovae and neutron star collision before the solar system formation.
Some theories claim that the nuclear processes of fusion, fission, and radioactive decay can possibly form gold. On the contrary, gold cannot be produced by alchemy or chemistry.
In addition, the quest for gold has been practiced thousands of years ago by the Egyptians, Greeks, and Romans. Today, the United States, China, Australia, Russia, and Canada hold the major gold producers in the world.
