I am God我就是神

The MC is a transmigrator from Earth and finds his soul in a vast empty space, where he then decides to create intelligent life to keep him company.
Starting from the the world's first inhabitants, and going throughout the ages. You follow a creation myth similar to that of the bible, where you get several stories about people who live in the era and how they go about their lives.
And as time goes on the relatively benign stories of the first arc become legend, those simple people who strive for the impossible are mentioned in passing by generations of their descendants and some very lucky few even become semi demi-god-like entities that others worship and who fight each other for dominance.
Those first cities become legendary mythical places, and the romances, deaths, villains and heroes all become part of the history. So much so that later on, only a handful of people remember there was even a creator that walked among them in the first place or that such places even existed.
Many characters die. Generations Fall. And even the laws of nature bend. But the only thing that remains constant is God, who watches the world.
It's a pretty rare story, and while it's only available to MTL as of this review. It's pretty much one of the best creation / god protagonist stories out there compared to others like Shepherding Humanity
