At the end Christian Bale calls on Eternity to originally thought to end all Gods he then requested his daughter. The thing is many in the comic book world believes that is not his actual daughter but Eternity transforming into "Mistress Love " from the comic book realm. She ends up they believe different from the comic book aging really fast and falling in love with Thor. Or just end up showing all kinds of insane powers higher Thor.
"One of the universe's most powerful entities, Mistress Love can control emotions related to love in any being, even on a universal scale. An abstract being, Mistress Love adopts M-Bodies to interact with others. Not truly a "mistress," she appears in any form or sex, frequently reflecting the desires of those who see her. To confront
Thanos, she chose a very feminine form; to Quasar, she appeared as his then-girlfriend, Kayla Ballantine; to the Enchantress, Mistress Love was a radiant male deity. Mistress Love can manipulate cosmic force, but prefers to act more peacefully.

Infinity Gauntlet, ranked Mistress Love at the same level of power as
Master Order,
Lord Chaos, and
Sire Hate, she is well above
Galactus,
One Above All (Celestial),
Kronos,
Odin,
Zeus, and
Stranger, but well below
Eternity and
Infinity, who in turn are well below
Living Tribunal.
