The Creator of Days

In the beginning, God created man and brought him life through His divine breath. Thousands of years after the fall of man, the world had died under a storm of nuclear fire. After the bombs had dropped and billions had perished, someone had suddenly unlocked infinite power and restored the world to its former state before leaving to beyond the nothingness to create a new world, one to fulfill a dream of creation and to cure the disappointment of reality. Decided to rewrite in the form of From Most High. Character shifts but the general idea is the same but the creator mc is not an isekai.
