I want to read novels about a god-like or immortal protagonist watching the world develop over thousands and millions of years. Examples: 1. She Was Both Called God, as Well as Satan 2. The Life of Mt. Hororyuu: The Forefather of all Life and Magic at 4.6 Billion Years Old Edit: Thanks for the recommendations!
The Breath of Creation would fit what you seem to be looking for. However, the author had dropped the title.
Hmmm, they're not god but Shepherding Humanity, Low Dimensional Game, Creating A Sandbox World are probably alright
Apart from the above, I can only recommend these two. 4.6 Billion Year Symphony of Evolution Building The Ultimate Fantasy
