After heaven was divided, the demons and angels went their own way. Of course, the demons thought that they could build a brand new place in hell, but due to the undying flames, they never got a chance to advance.
They waited for thousands of years but it was for naught since the flames were undying! This meant that their entire place would be in flames forever and ever.
This problem was soon solved by the few humans who entered the realm of demons, that is, the Hell. They held a power which was in between the Gods And the Demons.
That power and capacity enabled them to create a device that allowed the undying flames to cool down. Yes, they turned into lava which later became an essential part of Earth.
Because of the humans' help, Hell was renamed as Nether World or Netherland.
So how was the earth created exactly?
It was because of the punishment received by the humans from the Gods and the demons!
