Two significant events have shaken and continue to shake humanity since the dawn of time: birth and death. Looking around, one sees that everything has a beginning and an end. His children are born and die. So do animals, plants, and stars. Birth and death alternate without interruption.

Turning back the hands of time, one reaches the point of zero where a man and a woman bring the first children into the world. Who gave birth to them? He thinks and rethinks, and his mind creates God. God must have always existed and never dies.

In short, he discovers that only the ground he stands on, namely the earth, and the celestial universe that covers him, the sky, have always been there and time seems not to disturb them. These will be his first gods: The Sky and the Earth.

Moreover, influenced by the earthly world that surrounds him, he can think of God in no other way than as a duality, male and female, man and woman: the Sky as male and the Earth as female.
