San Diego residents were startled Wednesday as mysterious lights appeared in the sky over their city.

On Twitter, people posted pictures and video of the strange glowing orbs, with some speculating that the lights were not of this Earth.

So did San Diego get visited by aliens Wednesday night? Not so fast. 

A Navy spokesperson said the mysterious lights were simply part of a flare training exercise, according to CBS8

But others expressed doubt at that explanation.

The truth is out there.
