In the movie Elevation (2024), the creators of the Reapers are never definitively revealed on-screen.

What the movie actually shows

  • The Reapers are ultimately revealed to be machines, not organic monsters.
  • They first emerge from underground and seem to have been lying dormant there before the events of the film.
  • A post‑credits style tease suggests more creatures or machines may arrive from the sky via meteors, hinting at a larger, possibly extraterrestrial origin.

Do we know who created them?

  • The film itself does not confirm whether humans, aliens, or some other intelligence built the Reapers.
  • Fan discussions and theories suggest:
    • Alien creators using the Reapers to cull or control humanity.
* More speculative ideas that some advanced human faction or government might be behind them, but this is not supported in canon.

At this point, any answer naming a specific creator (like a government, company, or alien species) is speculative theory, not confirmed fact in the official story.

TL;DR:
The Reapers in Elevation are revealed to be machines, but the movie does not explicitly say who built them; their creators remain unknown, with only hints and fan theories pointing toward an alien origin.
