In comparative mythology, sky father is a term for a recurring concept of a sky god who is addressed as a "father", often the father of a pantheon. The concept of "sky father" may also be taken to include Sun gods with similar characteristics. The concept is complementary to an " earth mother".
"Sky Father" is a direct translation of the Vedic Dyaus Pita, etymologically descended from the same Proto-Indo-European deity as the Greek Zeus Pater and Roman Jupiter, all of which are reflexes of the same Proto-Indo-European deity's name, *Dyēus Ph₂tḗr. While there are numerous parallels adduced from outside of Indo-European mythology, the concept is far from universal (e.g. Egyptian mythology has a " Heavenly Mother").
Usage examples of "sky father".
Well, he had sons and nephews enough to carry on his blood, and Sky Father would greet him in the halls of the sun, perhaps grant him rebirth.
When the Christians first came here, they took great pains to teach our forefathers their religion, because they believed that theirs was the only way to reach the sky father.
