Speculations The first world was highly civilized probably like our modern world or more advanced

[D. Plant]

The First World shows human civilization fleeing. The "Maxim" you saw in the sky isn’t Uranus but Enel’s Maxim, which operates using lightning created by humans to escape to the moon (which is why Oda drew a moon).
We have Zunisha with Noah; Noah was meant to carry slaves and animals, while Zunisha transported the imperial family and its members. They were trying to store the Mother Flame’s energy as quickly as possible so they could leave their developed city while ensuring they had enough power to build another after the war settled down.
The Deity of Earth and the Hell Serpent were fighting against Nika using fire, making it difficult for the Maxim to leave the island and reach the moon but they succeded in the end.
No wonder there is a civilization on the moon, they are originally the humans of the First World who left because of the First War.

I may add from what I think of the origin of Lunarian. The story makes us think Lunarian was the God on second world. I think it was actually on the first world. They are the remnants of the winged who didn't flee to the Moon. In eternal destruction and darkness created by God of Earth and Serpent of Hell, they someone evolved to be able to create fires themselves and their body gets tougher. Or they did genetic mutation through science. Other remnants like the Shandians didn't evolve that much although they kinda looks similar. Joyboy defeated the Serpent of Hell but then he somehow killed by the God of Earth. The Lunarians just live on top of the Red Line created by God of Earth and Serpent of Hell.

Looking at this it looks like there are skyscrapers here, some actually look like nuclear power plants. I believe that the verse saying ''At the begining of the world there was flame'' it refers to the fact that the world was highly advanced and was powered by energy. Kind of goes in hand with some of what Vegapunk was saying about the ancient Kingdom being highly advanced and that his dream is to find an infinite source of energy for the world, that would be nuclear power or something like that.

Thoughts?

Yes the forbidden sun is probably nuclear energy

 

[MonsterKaido]

It was most likely similar to our modern world with skyscrapers and all. Humans probably brought too much destruction on earth making the earth god angry.

yeah, the ancient power source is the forbidden sun. as powerful as the mother flame is, and how its powerful enough to fuel the ancient weapons, the forbidden sun was even moreso.

i think this is related to the "drums of liberation" and brook using music to manipulate souls.

Is it a cycle?
The first world was filled with slaves and filled with flames so it probably sucked and was controlled by an evil entity who is then defeated by Nika, we get the second which is the ancient kingdom and technological advancement until Imu and the 20 kings defeat them and go back to having slaves and covering the world in darkness.
