Greek Mythology, Based on Hesiod's Theogony?

Question

I cannot find a straight answer

Who fathered the Titans, Cyclops, and Hecantonchires?

I cannot find plausible evidence toward a solid answer but im not that good at searching and my reasources are limited right now.

REMINDER: (MUST be according to Hesiod.)

My evidance says it was Uranus, (the heavens)

Answer 1

After the speaker declares that he has received the blessings of the Muses, and thanks them for giving him inspiration, he explains that spontaneously Chaos was. Chaos gives birth to Eros and Gaia (Earth), the more orderly and safe foundation that would serve as a home for the gods and mortals, came afterwards. Tartarus (both a place below the earth as well as a deity) and Eros (Desire) also came into existence from nothing. Eros serves an important role in sexual reproduction, before which children had to be produced by means of parthenogenesis. From Chaos came Erebos (Darkness) and Nyx (Night). However, Erebos and Nyx reproduced to make Aither (Brightness) and Hemera (Day). From Gaia came Ouranos (Sky), the Ourea (Mountains), and Pontus (Sea).

Ouranos mated with Gaia to create twelve Titans: Okeanos, Coeus, Crius, Hyperion, Lapetos, Theia, Rhea, Themis, Mnemosyne, Phoebe, Tethys, and Kronos and the Three Kyklopes (Cyclops): Brontes, Steropes, and Arges and the three Hecatonchires: Kottos, Briareos, and Gyges.
