Old World Reincarnation

The times rotate, the old and the new alternate. Is the new world replacing the old world, or is the new world just the rotation of the old world? What is the principle behind the birth of the black sun phenomenon, and the new generation gaining the power of the gods? What kind of fierce events will the new generation in the new world have with the giants at the end of the previous world? And is the new generation just a replacement for someone or something?
