The nahuatl legend of five Suns is fundamental to symbolically understand human evolution. With all the variants that exist regarding that in the beginning there was nothing and that's the Lord of the divine duality, Ometecuhtli, created Tonacatecuhtli and Tonacacihuatl, Lady and Lord of our flesh, so they could populate the land. They reproduced and had four children named: Red Tezcatlipoca, Black Tezcatlipoca, White Tezcatlipoca and Blue Tezcatlipoca.
Then the Tezcatlipocas thought that they should create a work so they would be worshiped as gods. Tezcatlipoca blue made a huge fire and the brothers placed themselves around to create human beings. Thus man was born and was Huehuecoyotl and a wife was created. They ordered them to have children and created the animals, mountains, seas, lakes and left them as a mission to worship the four gods. However, the work was not perfect because the Tlaltipac was in darkness, given that there was no sun.
