The reason for the extinction of the previous generation of humans was nuclear war and climate change. Earth's Ice Age had caused climate changes, and every time it was frozen, it would lead to the extinction of all life in the previous era. This extinction eventually led to nuclear war and the extinction of mankind by nuclear radiation. In addition, there was also a saying that advanced weapons and technology had led to the extinction of mankind. However, the specific details and background information were not mentioned in the search results provided, so a more specific answer could not be given.
In the previous era, humans threw nuclear bombs at each other, causing the earth to fall into destruction. Nuclear radiation filled the atmosphere, and the remaining human civilization directly returned to the primitive era.
The extinction of the previous era was due to humans throwing nuclear bombs at each other, causing the earth to fall into destruction. The nuclear bomb caused a devastating explosion, causing the Earth's atmosphere to be filled with nuclear radiation. This catastrophe caused human civilization to regress to the primitive era.
