Themes of power, gods, and explanations forming earth, and humans are at the centre of many creation myths, which is weird because people couldn't travel so they never would have communicated with each other.
A common element in many myths is the gods had absolute power. In the Mayan myth nobody challenged Tepeu or Gucumatz, and they could destroy or create anything that they envisioned. In the Inca myth Pachacamac was also unchallenged, and he could command his children to obey his orders or he could construct anything he craved. The Chinese myth said that Phan Ku was never confronted, and could erect anything he pleased.
In many myths they contain gods. The Inca god was Pachacamac who created humans, and sent his son, and daughter to educate the humans how to survive. The Mayan god was Gucumatz, and Tepeu who crafted animals, and humans so they could be praise, and the Chinese god was Pan Ku whose remains became parts of the earth.
Many myths have explanations of the creation of earth, and the creation of humans. The Mayan myth said humans were constructed out of corn, and the earth was fashioned when the gods imagined the characteristics of the earth. The Inca myth said that humans were created from rock that came from an enormous mountain of rock, and the earth was crafted when he produced the earth. The Chinese myth said the world was created from Pan Ku's death, while his fleas were the humans.
Even today humans sight, and understanding of the world is not perfect. This is what the Mayan, Inca, and Chinese myths have in common according to which was by Fiona Passantino. It also tells us that we think similarly.
