Who is the Father of Goddess Durga?

Now the question arises when both Kshar Purush / Kaal and Durga are in form and live together as husband-wife having material bodies

• How are both of them born? 
• Who is their father? 
• Do they have Children?

In Kabir Sagar, creation of the universe, the origin of Kshar Purush / Kaal and Durga is explained. The Almighty God KavirDev / Kabir (who is the creator of the entire universe) with his word power created this Kshar Purush from an egg and later Durga was born by the word power of Supreme God Kabir / KavirDev. So the father of Durga is none other than Almighty KavirDev.
