Who is the father of cosmology

In Manichaean cosmology, the world of darkness, which invaded the world of light in a lustful desire to mingle with the light, is ruled by five evil Archons, who together make up the Prince of Darkness.
The Father of Greatness parries the assault by evoking a number of entities, who sacrifice themselves and are absorbed by the Prince of Darkness; however, tricked by the Father of Greatness, their existence now depends on the light they absorbed.
To prevent the light particles from returning into their divine origin, they counter by giving birth to two demonic beings: Sakla and Nebroel.
As the strict anti-thesis of the pure light, the Prince of Darkness can not create ex nihilo, but only by copulation.
