So, life was birthed on a cold core planet?
I'm not entirely sure how I should have developed this.
I did a bit of research, and a planet with a solid core or frozen core, in this case, makes it very difficult for life.
In any case, I will do my best to showcase the evolution of life.
Oh, and one other thing, some may be wondering why this is all happening so quickly.
The development is told from the first and third person perspective of the "Infinite" who is a timeless being.
