Before there was gods, before life, death, skies, light, stars and planets.
There was only thr blank void of space, called abyss. (I think the abyss is asexual like plants and or some creatures)
And one day, it reproduce with itself and there was a big bang. (That's where we get the big bang from)
And the particles of the energy of the big bang. Created life, created death, and also created the first 2 deities (for greek).
the first deities, known as primordial gods, were Chaos, Gaia, Tartarus, and Eros, with Chaos being the first to exist, followed by Gaia (Earth), Tartarus (the Underworld Pit), and Eros (Love).
So I think how the world came to be was
the world emerged from Chaos, a primordial void, and then Gaia (Earth) and Uranus (Sky), the first beings, emerged from it, shaping the cosmos and giving birth to the Titans and other primordial beings.
And I do believe one day everything will go back to the abyss. And start all over again.
Not same as this life cycle. A different one... but unquie than the last.
