Aquaduct Canyon

At the bottom of the Quantum Seas lies a random crack in the seafloor. Scientists named it Aquaduct Canyon. But what´s most strange about it is that it is located in an area that should be flat ground. Thus, my theory: Is Aquaduct Canyon naturally occurring?

My Theory!

A spacecraft crashes into earth, it´s wingspan tipping into the ground creating the big crack. It lands under QC island, creating the unnatural shapes of the caverns.
