Two thousand five hundred years ago, Lao Tze wrote his work called the Tao Te Ching. In the very first chapter he states:
“The Nameless is the beginning of the Cosmic Universe;
The Named is the Mother of the myriad creatures.” (Ch1:V2)
Unmanifested energy and spirit stream into our 3-D world via stars – in our case, Father Sun. In the planets & moons it manifests in the form of physical matter - in our case, Mother Earth and her creatures. Together, the positive and negative combine to enable Life to occur.
 
In the Christian Bible, the God of Genesis makes the Heavens and Earth together, all at once, in the very first line. Humankind is created last as the crowning pinnacle of the work. (While most people like to quote the “second creation story” in chapter two, with the bit about the rib, I prefer the “first creation” in chapter one verse 27, where man and woman come into existence at once, in the same instance: “Male and Female he created them.”)

I am not sure what kind of creatures may exist in other Solar Systems and Galaxies, but here in our world we have the opportunity to use our consciousness and intention to be the connectors that complete the circuit between Sun and Earth, positive and negative force.
