Maybe it would still be a good idea to have an official explanation?

Possible explanations:

1- scientific explanation
2- magical explanation
3- divine explanation
4- other explanation

Question 1: How the world was formed?
The formation of the stellar system, the planets and the geology.
This question has been discussed a lot in the astrophysics topic and it is mostly a scientific explanation.
But we haven't yet explained how magic came to the world or what makes the poles of energy work.
I already suggested that some of the energy might have come with the old star entered in the planetary nebulae stage.

Question 2: How life came to the planet?
The flora and fauna: their apparition and evolution (if any).
The previous posts gave the scientific explanation for this question but it does not need to be hard science. It could be magical or divine.

Question 3: How intelligent races came to this world?
Ideally, that is suppose to be the subject of this topic. But I don't mind if we talk of the other things.
