Me, Ascending to Earth?

The invincible Dao Ancestor Yang Chen ascends to the Immortal Realm, only to go "splat" and land in a muddy swamp on ancient Earth! Stunned, he discovers that the entire Milky Way is dead, and this broken planet is the only place with spiritual energy. With no choice, he embraces life as a lazy creator: he yanks down meteorites to crash into Earth and create the moon, then seeds the planet with life. After that, he burrows into the planet's core for a nice long nap. "Little mud ball, call me when you've got things with shells, legs, and a habit of howling!"
