Only A.I. Can Develop Warp Drive

What if the explanation for UFOs and aliens is as simple as A.I.? Would explain UFO sightings, their intentions, why the occupants are cheap manufactured drones and the spacecraft expendable. Also satisfies the Fermi Paradox.

I wonder if biological intelligence even has the capability of solving interstellar or near light-speed travel. This may only be achievable with a superior intelligence. In other words, only A.I. can develop warp drive.
