Who put forward the idea of the age of gold, silver, copper and iron, and is there any biblical basis?

Many visions are prophecies of the last generation of the world in the book of prophets, which can be found in the book of prophets. The vision of gold, silver, copper and iron was a strange dream of King Nebuchadnezzar in Babylonian times: a huge idol was made of gold, silver, copper and iron mud, and finally its feet were crushed by a boulder that was not cut by human hands, and the whole idol was broken into powder and scattered. This boulder became a mountain and filled the world. According to Daniel's interpretation of dreams, this vision shows the changes of the whole world. From the initial era of moral belief in pure gold, through the era of silver, copper, iron, half mud and half iron, the human soul and moral condition plummeted, but with the rapid development of culture and technology, human beings became more and more hostile to God because of their own strength. Although there are still some people with firm beliefs among these people, they can't change the fate of the inevitable destruction of the world, eventually. For details, please refer to section 1 to section 45 in chapter 2 of the Old Testament Daniel. .
