Must Die at the Start? but I Am as Good as a God

At first it was just a crack between heaven and earth, and human civilization came to a standstill. Supernatural phenomena that science can no longer explain occur frequently, invading reality from various locations and dimensions and causing changes. Social rules begin to collapse, and death is no longer the end. There is no way of heaven, no golden finger, and no halo of the protagonist. When it was discovered that humans could not save the entire civilization, everyone was praying for the emergence of gods. A madman walked into the eyes of the world, responded to God's call, and wanted to cleanse the entire world.
