Final answer:
In the Popol Vuh, the first two things at the beginning of creation were the primordial sea and the thought of creation by the creators, preceding other elements such as the Earth, sky, humans, and celestial bodies.
Step-by-step explanation:
The Maya origin story Popol Vuh begins with the creation that occurs in an empty and silent space where only the sea, the sky, and the makers of the universe exist. Before the formation of the Earth and the sky, the creators were already present. They contemplated and then created the Earth.
There is no mention of the Sun, Moon, or humans at the very onset of the creation narrative in the Popol Vuh. Therefore, the first two things at the beginning of creation in the Popol Vuh were neither the Earth and the Sky, the Sun and the Moon, nor the Plants and the Animals, nor even the Gods and the Humans but rather the primordial sea and the thought of creation held by the creators.
